+# Animation System
+
+Source: `src/dusk/animation/`
+
+Lightweight keyframe-based value interpolation using fixed-point math throughout.
+
+---
+
+## Easing (`animation/easing.h`)
+
+`easingApply(type, t)` applies an easing function to a normalized time value `t ∈ [0, FIXED_ONE]` and returns the eased value in the same range.
+
+All functions are also callable directly:
+
+```c
+fixed_t t = FIXED(0.5f);
+fixed_t out = easingApply(EASING_IN_OUT_CUBIC, t);
+```
+
+Available easing types (all in `easingtype_t`):
+
+| Enum value | Curve |
+|---|---|
+| `EASING_LINEAR` | straight line |
+| `EASING_IN_SINE` / `OUT` / `IN_OUT` | sinusoidal |
+| `EASING_IN_QUAD` / `OUT` / `IN_OUT` | quadratic |
+| `EASING_IN_CUBIC` / `OUT` / `IN_OUT` | cubic |
+| `EASING_IN_QUART` / `OUT` / `IN_OUT` | quartic |
+| `EASING_IN_BACK` / `OUT` / `IN_OUT` | overshoots slightly |
+
+`EASING_FUNCTIONS[EASING_COUNT]` is a table of `easingfn_t` function pointers for when you need to pick an easing at runtime without a switch.
+
+---
+
+## Keyframes (`animation/keyframe.h`)
+
+```c
+typedef struct {
+  fixed_t time;          // time point this keyframe is at
+  fixed_t value;         // output value at this time
+  easingtype_t easing;   // easing to apply when interpolating toward the NEXT keyframe
+} keyframe_t;
+```
+
+Keyframe arrays should be sorted ascending by `time`.
+
+---
+
+## Animation (`animation/animation.h`)
+
+`animation_t` wraps a keyframe array and provides value lookup:
+
+```c
+keyframe_t frames[] = {
+  { FIXED(0.0f), FIXED(0.0f), EASING_LINEAR },
+  { FIXED(1.0f), FIXED(1.0f), EASING_IN_OUT_CUBIC },
+  { FIXED(2.0f), FIXED(0.0f), EASING_LINEAR },
+};
+
+animation_t anim;
+animationInit(&anim, frames, 3);
+
+fixed_t value = animationGetValue(&anim, FIXED(0.75f));   // interpolated
+```
+
+`animationGetValue` finds the surrounding keyframes for the given `time`, computes the local `t` within that segment, applies the keyframe's easing, and linearly interpolates between the two keyframe values.
+
+The animation does not own the keyframe array — it holds a pointer. Pass a static or long-lived array.
+
+---
+
+## Usage in the engine
+
+Entity animations (`entityanim_t`) do NOT use this system — they use a simple countdown timer (`animTime`) and a state enum. The `animation_t` system is intended for property animation: UI transitions, camera easing, visual effects, anything that needs a time → value curve.

+# Architecture
+
+## Platform abstraction
+
+Every subsystem that differs across platforms (display, input, asset loading, save, time, network, log) follows the same pattern:
+
+1. `src/dusk/<subsystem>/<subsystem>platform.h` — included by the public header. Contains `#include "path/to/platform-specific-header.h"` resolved by the build system include path.
+2. `src/dusk{platform}/<subsystem>/<subsystem>platform.h` — the actual platform-specific header included above (e.g. `src/duskgl/display/framebuffer/framebufferplatform.h`).
+3. The shared header (`src/dusk/<subsystem>/<subsystem>.h`) `#error`s at compile time if the platform doesn't define the expected macros/types.
+
+The active platform backends are selected by `DUSK_TARGET_SYSTEM` in CMake, which includes `cmake/targets/<system>.cmake`. That file sets compile definitions (`DUSK_LINUX`, `DUSK_SDL2`, `DUSK_OPENGL`, …) and links platform libraries.
+
+Platform source directories:
+- `src/duskgl/` — OpenGL rendering (used on Linux and as the GL layer for SDL2)
+- `src/dusksdl2/` — SDL2 window/input/time (Linux desktop)
+- `src/dusklinux/` — Linux filesystem/save/network
+- `src/duskdolphin/` — GameCube & Wii (GX renderer, libogc)
+- `src/duskpsp/` — PSP (GU renderer, PSPSDK)
+- `src/duskvita/` — PS Vita
+
+## Subsystem lifecycle
+
+All subsystems follow `init → update (per frame) → dispose`. Engine initialization order matters and is centralized in `engine.c`:
+
+```
+systemInit → timeInit → consoleInit → inputInit → assetInit →
+localeManagerInit → displayInit → uiInit → uiTextboxInit →
+cutsceneInit → rpgInit → networkInit → sceneInit
+```
+
+Dispose runs in reverse. Each call uses `errorChain()` to propagate failures.
+
+## Error handling
+
+Functions that can fail return `errorret_t` (a code + pointer to thread-local error state). Three core macros:
+
+```c
+errorThrow("message %s", arg);        // sets error, returns from current function
+errorChain(someCall());               // if someCall() fails, propagates and returns
+errorOk();                            // returns success
+```
+
+Check with `errorIsOk(ret)` / `errorIsNotOk(ret)`. The error state carries file/function/line info for a stack-like trace.
+
+## Fixed-point math
+
+`fixed_t` is `int32_t` with Q24.8 format (8 fractional bits, ~0.004 resolution). Use it for all world/game values:
+
+```c
+fixed_t x = FIXED(1.5);              // compile-time literal
+fixed_t y = fixedFromI32(3);         // runtime conversion
+fixed_t z = fixedMul(x, y);          // arithmetic
+float_t f = fixedToFloat(z);         // only where float is needed (e.g. GL uniforms)
+```
+
+## Code generation from CSV
+
+Several subsystems define their data in CSV files and have corresponding Python tools that generate C headers at build time (via CMake `add_custom_command`):
+
+| CSV | Tool | Output |
+|-----|------|--------|
+| `src/dusk/input/input.csv` | `tools/input/csv/` | input action enum + names |
+| `src/dusk/display/color.csv` | `tools/color/csv/` | color constants |
+| `src/dusk/rpg/item/item.csv` | `tools/item/csv/` | item enum + metadata |
+| `src/dusk/rpg/story/storyflag.csv` | `tools/story/csv/` | story flag enum + initial values |
+
+Generated headers are written to `build-<target>/generated/` and included via `target_include_directories`.
+
+## Asset system
+
+Assets are packed into `dusk.dsk` (a zip archive) at build time from the `assets/` directory. At runtime `asset.c` opens the archive and serves files from it.
+
+Loading is asynchronous: `assetLock()` registers a load request; the background thread calls the appropriate loader; call `assetRequireLoaded()` to block until ready. `assetUnlock()` / `assetUnlockEntry()` releases the entry so it can be reclaimed.
+
+Loaders are registered per type (`assetloadertype_t`) and live under `src/dusk/asset/loader/`. Platform-specific asset init (finding the .dsk file) is in `src/dusk{platform}/asset/`.
+
+## Display subsystem
+
+The display system is currently organized around immediate GPU-style rendering: `mesh_t` (vertex buffers), `shader_t` (GLSL on GL / TEV state on Dolphin), `texture_t`, and `framebuffer_t`. See [display-refactor.md](display-refactor.md) for the planned move to a render-queue model (needed for a future Saturn port).
+
+The `spritebatch_t` (`display/spritebatch/`) accumulates 2D quads and flushes in batches — the primary 2D drawing primitive used by the RPG layer.

+# Asset System
+
+Source: `src/dusk/asset/`
+
+All game assets are packed into `dusk.dsk` (a zip archive) at build time and served from it at runtime. The asset system manages async loading, reference counting, and platform-specific archive location.
+
+See [architecture.md](architecture.md#asset-system) for the high-level overview.
+
+---
+
+## Asset archive
+
+The archive is opened at `assetInit()`. `assetFileExists(filename)` checks for a file without loading it. The file path format inside the archive matches the layout of the `assets/` source directory.
+
+On each platform, `assetInitPlatform()` locates the `.dsk` file (e.g. adjacent to the binary on Linux, on the SD card on PSP).
+
+---
+
+## Entry lifecycle
+
+An `assetentry_t` represents one file being managed by the system. States:
+
+```
+NOT_STARTED → PENDING_ASYNC → LOADING_ASYNC → PENDING_SYNC → LOADING_SYNC → LOADED
+                                                                           └→ ERROR
+```
+
+- **PENDING_ASYNC / LOADING_ASYNC**: the background thread is handling I/O (file reads, decompression).
+- **PENDING_SYNC / LOADING_SYNC**: the main thread needs to finish loading (e.g. uploading to GPU), triggered during `assetUpdate()`.
+
+The async/sync split exists because GPU operations must happen on the main thread.
+
+---
+
+## Using assets
+
+```c
+// Acquire a loaded entry (blocks until loaded):
+assetentry_t *entry = assetLock(filename, ASSET_LOADER_TYPE_TEXTURE, &input);
+errorChain(assetRequireLoaded(entry));
+
+// Use the loaded data:
+texture_t *tex = &entry->data.texture.texture;
+
+// Release when done:
+assetUnlockEntry(entry);
+```
+
+`assetLock` finds-or-creates an entry and increments its reference count. `assetUnlock` / `assetUnlockEntry` decrements it; when it reaches zero the entry is reclaimed at the next `assetUpdate()`.
+
+To subscribe to async completion instead of blocking:
+```c
+eventSubscribe(&entry->onLoaded, myCallback, myUser);
+```
+
+---
+
+## Loader types
+
+| Type constant | File | Output struct accessed via |
+|---|---|---|
+| `ASSET_LOADER_TYPE_TEXTURE` | `.png` etc. | `entry->data.texture.texture` |
+| `ASSET_LOADER_TYPE_TILESET` | tileset descriptor | `entry->data.tileset.tileset` |
+| `ASSET_LOADER_TYPE_MESH` | mesh data | `entry->data.mesh.mesh` |
+| `ASSET_LOADER_TYPE_LOCALE` | `.po` file | internal to locale manager |
+| `ASSET_LOADER_TYPE_JSON` | `.json` | `entry->data.json.*` |
+
+Each loader type registers `loadAsync`, `loadSync`, and `dispose` callbacks in `ASSET_LOADER_CALLBACKS[]`.
+
+The async callback runs on the loader thread; the sync callback runs on the main thread during `assetUpdate()`. Most loaders do file I/O async and GPU upload sync.
+
+### Error handling inside loaders
+
+Use these macros instead of `errorThrow` / `errorChain` inside loader callbacks — they also set the entry state to ERROR:
+
+```c
+assetLoaderErrorChain(loading, someCall());
+assetLoaderErrorThrow(loading, "Descriptive message");
+```
+
+---
+
+## Low-level file I/O (`asset/assetfile.h`)
+
+`assetfile_t` wraps a `zip_file_t` handle and provides streaming reads:
+
+```c
+assetFileInit(&file, "textures/player.png", NULL, NULL);
+assetFileOpen(&file);
+assetFileRead(&file, buffer, size);
+assetFileClose(&file);
+assetFileDispose(&file);
+
+// Read entire file into a malloc'd buffer:
+uint8_t *buf; size_t size;
+assetFileReadEntire(&file, &buf, &size);   // caller frees buf
+```
+
+For line-by-line text parsing (`assetfilelinereader_t`):
+```c
+assetFileLineReaderInit(&reader, &file, readBuf, readBufSize, outBuf, outBufSize);
+while(!reader.eof) {
+  errorChain(assetFileLineReaderNext(&reader));
+  // reader.outBuffer contains the line, reader.lineLength its length
+}
+```
+
+---
+
+## Background loader thread
+
+`assetUpdateAsync(thread)` is the thread entry point. It calls `assetUpdate()` in a loop, sleeping briefly between iterations, until `threadShouldStop()` returns true. The main thread also calls `assetUpdate()` once per frame to process the sync phase.
+
+Up to `ASSET_LOADING_COUNT_MAX` (4) entries can be loading concurrently.
+Up to `ASSET_ENTRY_COUNT_MAX` (128) entries can exist at once.

+# Display Refactor Progress
+
+## Immediate Goal
+Render a 32x32 white square through the new render opcode stack on Linux.
+
+## Architecture (summary)
+See `.claude/display-refactor.md` for the full design.
+
+- `src/dusk/render/` -- opcode format + buffer + submission API (the *contract*).
+- Platform backends (e.g. `src/duskgl/`) consume the buffer and translate to native API calls.
+- `src/dusk/display/` -- orchestration shell only: `displayInit`, `displayUpdate`, `displayDispose`.
+- Scenes call `renderSprite(...)`, `renderClear(...)`. The backend executes the intent.
+
+## Opcode format (32 bytes)
+Every command starts with a 4-byte `ropheader_t` (opcode, flags, depth). Two commands defined:
+- `ROP_CLEAR` (32 bytes) -- clear with a color.
+- `ROP_DRAW_SPRITE` (32 bytes) -- screen-space int16 x/y/w/h + tint color.
+
+## Milestone 1 -- Archive + strip existing display deps ✓
+- [x] Old `src/dusk/display/` archived (now deleted from working tree via git).
+- [x] Old `src/duskgl/display/` removed (new GL renderer replaces it).
+- [x] `engine.c` stripped to minimal subsystems, set to `SCENE_TYPE_TEST`.
+- [x] `scene.c` stripped of old display/shader/screen references.
+- [x] `console.c` stripped of display deps.
+- [x] `ui/CMakeLists.txt` gutted (re-implementation deferred).
+- [x] `asset/loader/CMakeLists.txt` -- display loaders disabled.
+- [x] `asset/loader/assetloader.h` -- display loader types removed.

+- [x] `src/dusk/render/rop.h` -- `ropheader_t`, `ropclear_t`, `ropsprite_t`.
+- [x] `src/dusk/render/ropbuffer.h/.c` -- `ROPBUFFER` global, reset, alloc.
+- [x] `src/dusk/render/render.h/.c` -- `renderClear()`, `renderSprite()`.
+- [x] `src/dusk/render/CMakeLists.txt`.
+
+## Milestone 3 -- New minimal display shell ✓
+- [x] `src/dusk/display/display.h/.c` -- init/update/dispose, calls platform hooks.
+- [x] `src/dusk/display/displaystate.h` -- cull/depth/blend flags.
+- [x] `src/dusk/display/color.csv` + `CMakeLists.txt` -- color generation kept.
+
+## Milestone 4 -- GL backend ✓
+- [x] `src/duskgl/render/rendergl.h/.c`:
+  - GL 3.3 core shader (ortho projection, solid color, no texture yet).
+  - `renderGLInit` -- creates VAO/VBO/shader.
+  - `renderGLFlush(buf, w, h)` -- walks ROPBUFFER, GL calls per opcode.

+- [x] `src/duskgl/error/errorgl.h/.c` -- `errorGLCheck`.
+- [x] `src/duskgl/CMakeLists.txt`.
+- [x] `src/dusksdl2/display/displaysdl2.h/.c` updated:

+  - `displaySDL2Flush(ropbuffer_t *)` -- MakeCurrent + `renderGLFlush`.
+  - `displaySDL2Swap` -- SDL_GL_SwapWindow.
+- [x] `src/dusklinux/display/displayplatform.h` updated with new macros.
+
+## Milestone 5 -- Test scene ✓
+- [x] `SCENE_TYPE_TEST` added to `scenetype.h/.c`.
+- [x] `src/dusk/scene/test/scenetest.h/.c`:
+  - `renderClear(color(32, 32, 48, 255))` -- dark blue-grey background.
+  - `renderSprite(100, 100, 32, 32, COLOR_WHITE)` -- 32x32 white square.
+- [x] `engine.c` starts with `SCENE_TYPE_TEST`.
+
+## Milestone 6 -- Verified ✓
+- [x] Build succeeds with no errors (2026-06-18).
+- [x] Engine initializes: SDL window + GL context + shader + test scene.
+- [x] No crashes running for 5+ seconds.
+- [ ] 32x32 white square visually confirmed on screen.

+
+## Decisions log
+
+**2026-06-18** -- `color_t = color4b_t` (from generated `display/color.h`). The color generation pipeline (color.csv + Python tool) is kept in the new minimal `src/dusk/display/CMakeLists.txt`.
+
+**2026-06-18** -- `ROP_SIZE = 32`. All opcodes fixed 32 bytes. 3D quads will be 64 bytes when added later.
+
+**2026-06-18** -- Depth sort deferred. Buffer stores unsorted commands; painter platforms sort on flush. GL uses Z-buffer.
+
+**2026-06-18** -- Texture system not yet wired into the opcode pipeline. `ROP_DRAW_SPRITE` with `texture=0` uses solid tint color only (no sampler). Texture handle system comes next.
+
+**2026-06-18** -- GL backend uses GL 3.3 Core profile. Shader takes screen-space pixel coordinates and converts to clip space using window size queried from SDL each frame.
+
+**2026-06-18** -- `ROPBUFFER` is a global (4096 slots × 32 bytes = 128 KB). Reset at start of each frame in `displayUpdate`.

+# Display System
+
+Source: `src/dusk/display/`
+
+The display system is the rendering pipeline. It is abstracted across platforms via `displayplatform.h` — see [architecture.md](architecture.md) for the abstraction pattern. The current concrete backends are OpenGL (`src/duskgl/`) and GX/Dolphin (`src/duskdolphin/`).
+
+For the planned render-queue refactor (required for Saturn), see [display-refactor.md](display-refactor.md).
+
+---
+
+## Render / ROP system (`display/render/`)
+
+The ROP (Render OPcode) system is the low-level, backend-agnostic drawing API. All game drawing goes through this layer; backends (`rendergl.c`, `renderpsp.c`, `renderdolphin.c`) execute the commands at display flush time.
+
+### API (`display/render/render.h`)
+
+```c
+/* Clear the framebuffer */
+void renderClear(color_t color);
+
+/* 2D textured quad at pixel coordinates */
+void renderSprite(
+  int16_t x, int16_t y, int16_t w, int16_t h,
+  int16_t depth,                       /* 0=front … 32767=back */
+  rtexture_t texture, color_t tint
+);
+
+/* Set perspective projection for subsequent 3D draws */
+void renderSetProjection(
+  fixed_t fovY, fixed_t aspect, fixed_t nearZ, fixed_t farZ
+);
+
+/* Set camera position/target for subsequent 3D draws */
+void renderSetView(
+  int16_t eyeX, int16_t eyeY, int16_t eyeZ,
+  int16_t tgtX, int16_t tgtY, int16_t tgtZ
+);
+
+/* World-space quad: center point + right half-extent + up half-extent */
+void renderQuad3D(
+  int16_t cx, int16_t cy, int16_t cz,
+  int16_t rx, int16_t ry, int16_t rz,
+  int16_t ux, int16_t uy, int16_t uz,
+  int16_t depth,
+  rtexture_t texture, color_t tint
+);
+
+/* Create / dispose an 8-bit indexed palette texture */
+rtexture_t renderTextureCreate(
+  uint16_t w, uint16_t h,
+  const uint8_t *indices,    /* w×h pixel indices (0-255) */
+  const color_t *palette     /* 256 RGBA colour entries */
+);
+void renderTextureDispose(rtexture_t tex);
+
+/* Mutable pointers to the texture's CPU-side data.
+ * Write directly to these; the next draw call picks up the changes.
+ *   GL:      dirty flag set on getter call; glTexSubImage2D at next bind.
+ *   PSP:     re-pads indices and converts palette → ABGR at bind time.
+ *   Dolphin: re-tiles CI8 and converts palette → RGB5A3 at bind time. */
+color_t *renderTextureGetPalette(rtexture_t tex);  /* color_t[256]  */
+uint8_t *renderTextureGetIndices(rtexture_t tex);  /* uint8_t[w*h]  */
+```
+
+### Coordinate conventions
+
+| Domain | Type | Scale | Notes |
+|---|---|---|---|
+| 3D world positions | `int16_t` | 1 unit = 1 cm | Matches PS1 GTE / N64 RSP native format |
+| Camera/projection params | `fixed_t` | Q24.8 | `FIXED(x)` for literals |
+| 2D screen positions | `int16_t` | pixels | Origin top-left |
+| UV coords | `uint8_t` | 0–255 → 0.0–1.0 | Stored in ROP structs |
+
+### Palettized textures
+
+All textures are 8-bit indexed. `renderTextureCreate` takes:
+- `indices`: one `uint8_t` per pixel (0–255), row-major
+- `palette`: exactly **256** `color_t` RGBA entries
+
+**Per-platform storage:**
+
+| Platform | CPU source of truth | GPU/native format | When derived |
+|---|---|---|---|
+| GL (Linux/Vita) | `color_t palette[256]` + `uint8_t *cpuIndices` in slot | `GL_R8` index tex + `GL_RGBA` 256×1 palette tex | Lazy: dirty flag set by getter, `glTexSubImage2D` at next bind |
+| PSP | `color_t palette[256]` + unpadded `uint8_t *cpuIndices` | Stride-padded indices (POT ≥ 8) + ABGR8888 CLUT in shared `pspAbgrBuf` | Every `bindTexture` call; dcache-flushed before GU reads |
+| Dolphin/GC/Wii | `color_t palette[256]` + unpadded `uint8_t *cpuIndices` | CI8 tiled (8×4 tiles, 32 B/tile) + RGB5A3 TLUT in `tlutData` | Every `bindTexture` call; `DCFlushRange` before GX load |
+
+**GL palette shader detail**: The fragment shader samples the R8 index texture, converts the normalised float back to an exact texel centre with `raw*(255/256) + 0.5/256`, then looks up the 256×1 palette texture. This gives pixel-exact results for all 256 index values and allows independent real-time updates to indices or palette.
+
+**Dolphin RGB5A3 encoding**:
+- Opaque (`a == 255`): bit 15 = 1, RGB555
+- Transparent: bit 15 = 0, A3RGB4 (alpha quantised to 3 bits — dithered transparency is planned for a future pass)
+
+### ROP buffer (`display/render/ropbuffer.h` / `rop.h`)
+
+Commands are written into `ROPBUFFER` (a static byte array) then replayed by the backend at flush time. All ops are fixed-size aligned structs:
+
+| Op | Struct | Size |
+|---|---|---|
+| `ROP_CLEAR` | `ropclear_t` | 32 bytes |
+| `ROP_DRAW_SPRITE` | `ropsprite_t` | 32 bytes |
+| `ROP_SET_PROJECTION` | `ropprojection_t` | 32 bytes |
+| `ROP_SET_VIEW` | `ropview_t` | 32 bytes |
+| `ROP_DRAW_QUAD_3D` | `ropquad3d_t` | 64 bytes |
+| `ROP_DRAW_TILEMAP_CHUNK` | `roptilemapc_t` | 32 bytes |
+
+`ropOpSize(op)` returns the byte size for any op. Backends iterate with `offset += ropOpSize(op)`.
+
+### Texture handles (`display/render/rtexture.h`)
+
+`rtexture_t` is a `uint16_t` index into the platform's texture table. `RTEXTURE_NONE` (0 or a sentinel) means "white fallback". Tables are platform-static; handles are valid until `renderTextureDispose` is called.
+
+### Tilemap chunk handles (`display/render/rtilemapchunk.h`)
+
+`rtilemapchunk_t` is a `uint16_t` index into the platform's chunk table. `RTILEMAPCHUNK_INVALID` (0) means no-op. Chunks are pre-built at map load time; each backend constructs its native draw structure once (VAO+VBO on GL, display list on PSP/GX/N64) and the ROP entry costs only a handle lookup + single native draw call per frame.
+
+```c
+/* Build once at map load */
+rtilemapchunk_t chunk = renderTilemapChunkCreate(
+  chunkW, chunkH,     /* size in tiles */
+  tileW, tileH,       /* pixels per tile */
+  tileset,            /* rtexture_t of the packed tileset */
+  tileIndices         /* uint8_t[chunkW*chunkH], row-major tile indices */
+);
+
+/* Each frame for visible chunks */
+renderTilemapChunk(screenX, screenY, depth, chunk);
+
+/* At map unload */
+renderTilemapChunkDispose(chunk);
+```
+
+Animated tiles should be drawn on top as separate `renderSprite()` calls; the chunk itself is treated as static geometry and never rebuilt at runtime.
+
+**Per-platform build:**
+
+| Platform | What's built at create time | Draw cost per frame |
+|---|---|---|

+
+## Initialization order
+
+Within the display system, init must follow this order (enforced in `engine.c`):
+
+```
+displayInit → uiInit → uiTextboxInit
+```
+
+Within `displayInit`, the platform typically initialises: framebuffer → screen → shader list → textures → spritebatch → text system.
+
+---
+
+## `display_t` / `displaystate_t`
+
+`display_t DISPLAY` is the global display instance (type alias for `displayplatform_t`).
+
+`displaystate_t` carries per-draw-call render state flags:
+
+```c
+DISPLAY_STATE_FLAG_CULL       // face culling
+DISPLAY_STATE_FLAG_DEPTH_TEST // depth testing
+DISPLAY_STATE_FLAG_BLEND      // alpha blending
+```
+
+Set state before drawing with `displaySetState(state)`.
+
+---
+
+## Screen (`display/screen/`)
+
+`screen_t SCREEN` manages the logical viewport that game content renders into. On dynamic-size platforms (Linux/SDL2) the screen can differ from the native window/framebuffer resolution.
+
+Screen modes:
+```
+SCREEN_MODE_BACKBUFFER           — maps 1:1 to backbuffer
+SCREEN_MODE_FIXED_SIZE           — fixed pixel dimensions
+SCREEN_MODE_ASPECT_RATIO         — fixed aspect, scale to fit
+SCREEN_MODE_FIXED_HEIGHT         — fixed height, width scales
+SCREEN_MODE_FIXED_WIDTH          — fixed width, height scales
+SCREEN_MODE_FIXED_VIEWPORT_HEIGHT — fixed viewport height
+```
+
+The linux target defines `DUSK_DISPLAY_SCREEN_HEIGHT=240`, producing a 240p fixed-height viewport.
+
+Render loop usage:
+```c
+screenBind();       // set up viewport, projection
+// ... draw game content ...
+screenUnbind();
+screenRender();     // blit to backbuffer / current framebuffer
+```
+
+`SCREEN.width` / `SCREEN.height` are the logical dimensions used for world-to-screen math — always prefer these over the framebuffer dimensions.
+
+---
+
+## Framebuffer (`display/framebuffer/`)
+
+`framebuffer_t FRAMEBUFFER_BACKBUFFER` is the platform backbuffer. `FRAMEBUFFER_BOUND` points to the currently-bound framebuffer (or `NULL` for backbuffer).
+
+```c
+frameBufferInitBackBuffer();                        // called once at startup
+frameBufferBind(fb);                                // NULL → backbuffer
+frameBufferClear(FRAMEBUFFER_CLEAR_COLOR | FRAMEBUFFER_CLEAR_DEPTH, COLOR_BLACK);
+frameBufferGetWidth(fb) / frameBufferGetHeight(fb) / frameBufferGetAspect(fb);
+```
+
+On platforms with `DUSK_DISPLAY_SIZE_DYNAMIC`, off-screen framebuffers can be created with `frameBufferInit(fb, w, h)` and disposed with `frameBufferDispose(fb)`. Fixed-resolution platforms (PSP, GameCube) only ever use the backbuffer.
+
+---
+
+## Mesh (`display/mesh/`)
+
+`mesh_t` is a vertex buffer. The type is `meshplatform_t` (e.g. a VAO+VBO on GL, a GX display list on Dolphin).
+
+```c
+meshInit(&mesh, MESH_PRIMITIVE_TYPE_TRIANGLES, vertexCount, verticesPtr);
+meshFlush(&mesh, offset, count);  // upload CPU vertices → GPU
+meshDraw(&mesh, offset, count);   // draw; pass -1 for count to draw all
+meshDispose(&mesh);
+```
+
+**Key distinction**: `meshFlush` uploads data to GPU memory; `meshDraw` issues the draw call. For static geometry (chunk meshes) you call `meshFlush` once on load, then `meshDraw` every frame. For dynamic geometry (spritebatch) you `meshFlush` + `meshDraw` each frame.
+
+`meshvertex_t` (`display/mesh/meshvertex.h`) contains:
+- `float_t uv[2]` — texture coordinates
+- `float_t pos[3]` — position
+- Optionally `color_t color` if `MESH_ENABLE_COLOR` is defined (off by default)
+
+Primitive mesh generators live alongside `mesh.h`: `quad.h`, `plane.h`, `cube.h`, `sphere.h`, `capsule.h`, `triprism.h`.
+
+---
+
+## Shader (`display/shader/`)
+
+`shader_t` is `shaderplatform_t` (GLSL program on GL, TEV state block on Dolphin).
+
+```c
+shaderInit(&shader, &definition);
+shaderBind(&shader);
+shaderSetMatrix(&shader, "uModel", modelMat);
+shaderSetTexture(&shader, "uTexture", &texture);
+shaderSetColor(&shader, "uColor", COLOR_WHITE);
+shaderSetMaterial(&shader, &material);
+shaderDispose(&shader);
+```
+
+### Shader list (`display/shader/shaderlist.h`)
+
+The engine maintains a small set of built-in shaders in `SHADER_LIST_DEFS[]`. Currently only one is defined:
+
+- `SHADER_LIST_SHADER_UNLIT` → `SHADER_UNLIT` — unlit textured/colored rendering, used for all world and entity drawing.
+
+`shaderListInit()` compiles/uploads all built-in shaders and sets shared projection/view matrices. Call once after display init.
+
+### Materials (`display/shader/shadermaterial.h`)
+
+`shadermaterial_t` is a union of all shader-specific material structs. Currently only `shaderunlitmaterial_t`:
+
+```c
+shadermaterial_t mat = {
+  .unlit = {
+    .color = COLOR_WHITE,
+    .texture = &myTexture,   // NULL for solid color
+  }
+};
+shaderSetMaterial(&SHADER_UNLIT, &mat);
+```
+
+---
+
+## Texture (`display/texture/`)
+
+```c
+textureInit(&texture, width, height, format, data);
+textureDispose(&texture);
+```
+
+Width and height **must be powers of two** (asserted at init time).
+
+`textureformat_t` is `textureformatplatform_t`. Supported formats vary by platform; the common ones are `TEXTURE_FORMAT_RGBA` and `TEXTURE_FORMAT_PALETTE`.
+
+`texturedata_t` is a union:
+```c
+// RGBA:
+data.rgbaColors = colorArray;
+
+// Paletted:
+data.paletted.indices = indexArray;
+data.paletted.palette = &palette;   // palette color count must be power of two
+```
+
+**Built-in textures** (defined in `texture.c`, no asset loading needed):
+- `TEXTURE_WHITE` — 4×4 solid white
+- `TEXTURE_TEST` — 4×4 black/magenta checkerboard
+
+### Palette (`display/texture/palette.h`)
+
+Up to `PALETTE_COUNT` (6) global palettes in `PALETTES[]`, each holding up to `PALETTE_COLOR_COUNT` (255) `color_t` entries.
+
+### Tileset (`display/texture/tileset.h`)
+
+A tileset slices a texture into a grid of equal-sized tiles. Used by fonts and UI frames. The tileset does not own the texture — it references a `texture_t *`.
+
+---
+
+## SpriteBatch (`display/spritebatch/`)
+
+The primary 2D/billboard drawing primitive. Accumulates `spritebatchsprite_t` quads and flushes them in batches of `SPRITEBATCH_FLUSH_COUNT` (16) sprites at a time.
+
+```c
+// Per frame:
+spriteBatchClear();
+spriteBatchBuffer(sprites, count, &SHADER_UNLIT, material);  // auto-flushes when batch full
+spriteBatchFlush();  // flush remaining
+
+// Low-level: write directly to an external mesh (for baking static geometry):
+spriteBatchBufferToMesh(sprites, count, vertices, verticesSize);
+```
+
+`spritebatchsprite_t`:
+```c
+typedef struct {
+  vec3 min, max;     // 3D bounding box
+  vec2 uvMin, uvMax; // texture region
+} spritebatchsprite_t;
+```
+
+The global `SPRITEBATCH` and its vertex backing array `SPRITEBATCH_VERTICES[]` are defined externally to the struct to satisfy alignment requirements on certain platforms.
+
+---
+
+## Text (`display/text/`)
+
+Text rendering uses `FONT_DEFAULT` (loaded during `textInit()`), which references a texture and a tileset. Characters start at ASCII `!` (`TEXT_CHAR_START`).
+
+```c
+textDraw(x, y, "Hello", COLOR_WHITE, &FONT_DEFAULT);
+textMeasure("Hello", &FONT_DEFAULT, &outWidth, &outHeight);
+
+// Single-char sprite for manual layout:
+spritebatchsprite_t s = textGetSprite(pos, 'A', &FONT_DEFAULT);
+```
+
+`font_t` holds a `texture_t *` and a `tileset_t *` — both are owned by the asset system, not the font struct.

+# Input System
+
+Source: `src/dusk/input/`
+
+The input system decouples physical hardware buttons from logical game actions via a binding layer. Actions are defined in `src/dusk/input/input.csv` and code-generated into `inputaction_t` enum values — see [architecture.md](architecture.md#code-generation-from-csv).
+
+---
+
+## Concepts
+
+**Button** (`inputbutton_t`) — a physical input source: a keyboard scancode, gamepad button, gamepad axis, or pointer axis. The available button types depend on which `DUSK_INPUT_*` defines are active for the target platform.
+
+**Action** (`inputaction_t`) — a logical game input (e.g. `INPUT_ACTION_UP`, `INPUT_ACTION_CONFIRM`, `INPUT_ACTION_RAGEQUIT`). Each action accumulates a float value `[0.0, 1.0]` from all buttons bound to it.
+
+**Binding** — a many-to-one mapping from buttons to actions. Bindings are registered at runtime with `inputBind(button, action)`.
+
+---
+
+## Querying actions
+
+```c
+// Boolean helpers (current frame):
+inputIsDown(action)        // value > 0 this frame
+inputPressed(action)       // down this frame but not last
+inputReleased(action)      // down last frame but not this
+
+// Last frame state:
+inputWasDown(action)
+
+// Raw float value:
+inputGetCurrentValue(action)   // [0.0, 1.0]
+inputGetLastValue(action)
+
+// Axis helpers — combine two opposing actions into a signed float:
+float_t h = inputAxis(INPUT_ACTION_LEFT, INPUT_ACTION_RIGHT);  // -1.0 to 1.0
+inputAxis2D(negX, posX, negY, posY, result);   // fills vec2
+inputAngle2D(negX, posX, negY, posY, result);  // atan2-based normalized direction
+
+// Deadzone:
+float_t clean = inputDeadzone(rawValue, 0.1f);
+```
+
+---
+
+## Dynamic values (`DUSK_TIME_DYNAMIC`)
+
+On platforms with variable frame rates, each action also tracks `dynamicDelta`-scaled values:
+
+```c
+inputGetCurrentValueDynamic(action)
+inputGetLastValueDynamic(action)
+```
+
+These account for the actual time elapsed since the last frame, so movement calculated from them is frame-rate independent.
+
+---
+
+## Events on actions
+
+Each `inputactiondata_t` exposes `onPressed` and `onReleased` events:
+
+```c
+eventSubscribe(&INPUT.actions[INPUT_ACTION_CONFIRM].onPressed, myCallback, myUser);
+```
+
+The callback signature is `void cb(void *params, void *user)`. `params` is always `NULL` for input events.
+
+---
+
+## Buttons and bindings
+
+Physical buttons are typed via `inputbuttontype_t`:
+
+| Constant | When available | Payload |
+|---|---|---|
+| `INPUT_BUTTON_TYPE_KEYBOARD` | `DUSK_INPUT_KEYBOARD` | `inputscancode_t` |
+| `INPUT_BUTTON_TYPE_GAMEPAD` | `DUSK_INPUT_GAMEPAD` | `inputgamepadbutton_t` |
+| `INPUT_BUTTON_TYPE_GAMEPAD_AXIS` | `DUSK_INPUT_GAMEPAD` | axis + positive direction flag |
+| `INPUT_BUTTON_TYPE_POINTER` | `DUSK_INPUT_POINTER` | `inputpointeraxis_t` |
+
+Button names and default bindings are defined in `input.csv`. Look up a button by name:
+```c
+inputbutton_t btn = inputButtonGetByName("keyboard_w");
+inputBind(btn, INPUT_ACTION_UP);
+```
+
+`INPUT_BUTTON_DATA[]` holds runtime state (current/last raw values) for every physical button.
+
+---
+
+## Platform platform-specific reads
+
+`inputButtonGetValuePlatform(button)` is the one required platform function — it returns the current raw `[0.0, 1.0]` value for a button. The platform implementations live in `src/dusk{platform}/input/`.

+# Cutscenes
+
+Two distinct layers: a low-level engine sequencer (`src/dusk/cutscene/`) and a higher-level RPG wrapper (`src/dusk/rpg/cutscene/`). Almost all game code works with the RPG layer.
+
+---
+
+## Engine sequencer (`src/dusk/cutscene/`)
+
+`cutscene_t CUTSCENE` is a minimal event runner with up to `CUTSCENE_EVENT_COUNT_MAX` (16) `cutsceneevent_t` slots. Each event has three callbacks:
+
+```c
+typedef struct {
+  errorret_t (*onStart)(void);
+  errorret_t (*onUpdate)(void);
+  errorret_t (*onEnd)(void);
+} cutsceneevent_t;
+```
+
+API:
+```c
+cutscenePlay(events, count);   // copy events array and start from index 0
+cutsceneAdvance();             // end current event, start next (deactivates after last)
+cutsceneStop();                // abort immediately
+cutsceneIsActive();            // bool
+```
+
+This layer is primarily used by the RPG cutscene system — game code doesn't normally touch it directly.
+
+---
+
+## RPG cutscene layer (`src/dusk/rpg/cutscene/`)
+
+### Data structures
+
+A `cutscene_t` is just a pointer to an item array and a count:
+
+```c
+typedef struct cutscene_s {
+  const cutsceneitem_t *items;
+  uint8_t itemCount;
+} cutscene_t;
+```
+
+A `cutsceneitem_t` is a tagged union of all item types:
+
+```c
+typedef struct cutsceneitem_s {
+  cutsceneitemtype_t type;
+  union {
+    cutscenetext_t    text;      // display text in textbox
+    cutscenecallback_t callback; // call a void(*)(void) function
+    cutscenewait_t    wait;      // pause for a fixed_t duration (seconds)
+    const cutscene_t *cutscene;  // nest another cutscene
+  };
+} cutsceneitem_t;
+```
+
+### Item types
+
+| Type constant | Payload | Behaviour |
+|---|---|---|
+| `CUTSCENE_ITEM_TYPE_TEXT` | `cutscenetext_t` — `text[256]` + `rpgtextboxpos_t position` | Shows textbox; advances on player confirm input |
+| `CUTSCENE_ITEM_TYPE_CALLBACK` | `cutscenecallback_t` (function pointer) | Calls the function once, then immediately advances |
+| `CUTSCENE_ITEM_TYPE_WAIT` | `cutscenewait_t` (a `fixed_t` in seconds) | Counts down `animTime` each frame, then advances |
+| `CUTSCENE_ITEM_TYPE_CUTSCENE` | `const cutscene_t *` | Plays the nested cutscene before continuing |
+
+### Runtime state
+
+`cutscenesystem_t CUTSCENE_SYSTEM` tracks:
+- `scene` — pointer to the active `cutscene_t`
+- `currentItem` — index into `scene->items[]`
+- `data` — per-item runtime data (`cutsceneitemdata_t`, currently just `cutscenewaitdata_t`)
+- `mode` — the current `cutscenemode_t`
+
+API:
+```c
+cutsceneSystemStartCutscene(cutscene);   // begin playing a cutscene
+cutsceneSystemNext();                    // advance to next item
+cutsceneSystemUpdate();                  // called each frame from rpgUpdate
+cutsceneSystemGetCurrentItem();          // inspect active item
+```
+
+### Cutscene mode (`cutscenemode.h`)
+
+Each item can run in one of three modes:
+
+```c
+CUTSCENE_MODE_NONE           // no cutscene active
+CUTSCENE_MODE_FULL_FREEZE    // pause everything (not yet used)
+CUTSCENE_MODE_INPUT_FREEZE   // player input blocked (default: CUTSCENE_MODE_INITIAL)
+CUTSCENE_MODE_GAMEPLAY       // player can still move during cutscene
+```
+
+`cutsceneModeIsInputAllowed()` is checked by `entityUpdate()` before invoking the movement callback — the player cannot walk when in INPUT_FREEZE mode.
+
+### Defining a cutscene
+
+Cutscenes are defined as `static const` arrays in header files under `rpg/cutscene/scene/`. Example (`testcutscene.h`):
+
+```c
+static const cutsceneitem_t MY_CUTSCENE_ITEMS[] = {
+  {
+    .type = CUTSCENE_ITEM_TYPE_TEXT,
+    .text = { .text = "Hello!", .position = RPG_TEXTBOX_POS_BOTTOM }
+  },
+  {
+    .type = CUTSCENE_ITEM_TYPE_WAIT,
+    .wait = FIXED(1.5f)
+  },
+  {
+    .type = CUTSCENE_ITEM_TYPE_CUTSCENE,
+    .cutscene = &ANOTHER_CUTSCENE
+  },
+};
+
+static const cutscene_t MY_CUTSCENE = {
+  .items = MY_CUTSCENE_ITEMS,
+  .itemCount = sizeof(MY_CUTSCENE_ITEMS) / sizeof(cutsceneitem_t)
+};
+```
+
+Attach to an NPC via its interact component:
+```c
+entity->interact.type = ENTITY_INTERACT_CUTSCENE;
+entity->interact.data.cutscene = &MY_CUTSCENE;
+```
+
+---
+
+## Textbox (`src/dusk/rpg/rpgtextbox.h`)
+
+`rpgtextbox_t RPG_TEXTBOX` is the global textbox state:
+
+```c
+typedef struct {
+  rpgtextboxpos_t position;      // RPG_TEXTBOX_POS_TOP or RPG_TEXTBOX_POS_BOTTOM
+  bool_t visible;
+  char_t text[RPG_TEXTBOX_MAX_CHARS];   // 256 chars
+} rpgtextbox_t;
+```
+
+API:
+```c
+rpgTextboxShow(position, text);   // copies text, sets visible = true
+rpgTextboxHide();                 // sets visible = false
+rpgTextboxIsVisible();            // bool
+```
+
+The textbox state is read by `ui/uitextbox.c` during the UI render pass to draw the dialogue box on screen. `rpgtextbox.c` itself does no rendering.

+# Entities
+
+Source: `src/dusk/rpg/entity/`
+
+---
+
+## Storage
+
+Entities live in a single fixed global array:
+
+```c
+entity_t ENTITIES[ENTITY_COUNT];   // ENTITY_COUNT = 64
+```
+
+A slot is "empty" when `entity->type == ENTITY_TYPE_NULL`. Never allocate entity memory dynamically — always find a free slot with `entityGetAvailable()`, which returns its index (`0xFF` if none free).
+
+---
+
+## `entity_t` structure
+
+```c
+typedef struct entity_s {
+  uint8_t id;                  // index in ENTITIES[]
+  entitytype_t type;           // ENTITY_TYPE_NULL / PLAYER / NPC
+  entitytypedata_t data;       // union: player_t | npc_t
+
+  entitydir_t direction;       // facing direction (N/S/E/W)
+  fixed_t position[3];         // current sub-tile position (x, y, z)
+  fixed_t lastPosition[3];     // position before last move (for interpolation)
+
+  entityanim_t animation;      // IDLE / TURN / WALK
+  fixed_t animTime;            // countdown timer for current animation
+
+  entityinteract_t interact;   // optional interact component
+} entity_t;
+```
+
+---
+
+## Type system
+
+Entity types are defined in `entitytype.h` using the enum+integer-typedef pattern:
+
+```c
+typedef enum { ENTITY_TYPE_NULL, ENTITY_TYPE_PLAYER, ENTITY_TYPE_NPC, ENTITY_TYPE_COUNT } entitytype_enum_t;
+typedef uint8_t entitytype_t;
+```
+
+Each type has a `entitycallback_t` entry in the `ENTITY_CALLBACKS[ENTITY_TYPE_COUNT]` static table:
+
+```c
+typedef struct {
+  void (*init)(entity_t *entity);
+  void (*movement)(entity_t *entity);
+  bool_t (*interact)(entity_t *player, entity_t *entity);
+} entitycallback_t;
+```
+
+Callbacks not applicable to a type are `NULL`; `entityUpdate()` guards against this before calling.
+
+Type-specific data sits in `entitytypedata_t` (a union of `player_t` and `npc_t`). Currently both are stubs (`void *nothing`).
+
+---
+
+## Direction (`entitydir.h`)
+
+```c
+ENTITY_DIR_NORTH / EAST / SOUTH / WEST
+```
+
+Aliases: `UP = NORTH`, `DOWN = SOUTH`, `LEFT = WEST`, `RIGHT = EAST`.
+
+Utilities:
+- `entityDirGetOpposite(dir)` — returns the opposite direction.
+- `entityDirGetRelative(dir, &relX, &relY)` — fills in the ±1 XY delta for that direction.
+- `assertValidEntityDir(dir, msg)` — assertion macro.
+
+---
+
+## Animation (`entityanim.h`)
+
+```c
+ENTITY_ANIM_IDLE   // standing still
+ENTITY_ANIM_TURN   // turning to a new direction (ENTITY_ANIM_TURN_DURATION = FIXED(0.06))
+ENTITY_ANIM_WALK   // mid-step (ENTITY_ANIM_WALK_DURATION = FIXED(0.1))
+```
+
+`entityAnimUpdate(entity)` decrements `animTime` each frame and transitions back to `IDLE` when it reaches zero.
+
+`entityCanWalk(entity)` / `entityCanTurn(entity)` both return true only when `animation == ENTITY_ANIM_IDLE`.
+
+The renderer interpolates between `lastPosition` and `position` using `animTime / WALK_DURATION` to produce smooth motion even at low frame rates.
+
+---
+
+## Movement
+
+`entityWalk(entity, direction)`:
+
+1. Converts `entity->position` to a `worldpos_t` (truncates fractional part).
+2. Applies the directional delta to get `newPos`.
+3. Checks the current and target tiles for ramp raise/fall logic (see [world.md](world.md)).
+4. Checks `ENTITIES[]` for another entity occupying `newPos` — blocks if found.
+5. On success: copies `position` to `lastPosition`, updates `position` to `newPos` (via `worldPosToFixed`), sets `animation = ENTITY_ANIM_WALK`.
+
+`entityTurn(entity, direction)`: sets `direction` and starts a brief turn animation.
+
+---
+
+## Interaction (`entityinteract.h`)
+
+The `entityinteract_t` component is embedded in every entity. It is optional — set `type = ENTITY_INTERACT_NULL` for non-interactable entities.
+
+```c
+typedef enum {
+  ENTITY_INTERACT_NULL,
+  ENTITY_INTERACT_CUTSCENE,   // plays a cutscene_t *
+  ENTITY_INTERACT_PRINT,      // prints a short message[32]
+} entityinteracttype_t;
+```
+
+`entityInteractWith(player, target)` dispatches:
+1. If the interact component's `type != NULL`, handles it (starts the cutscene or prints the message).
+2. Otherwise falls back to `ENTITY_CALLBACKS[type].interact` if set.
+
+---
+
+## Player (`player.h` / `player.c`)
+
+`playerInit()` is called via `ENTITY_CALLBACKS[ENTITY_TYPE_PLAYER].init`.
+
+`playerInput(entity)` is the movement callback. It reads `PLAYER_INPUT_DIR_MAP[]` — a static table mapping input actions (`INPUT_ACTION_UP/DOWN/LEFT/RIGHT`) to entity directions — and calls `entityWalk` or `entityTurn` accordingly.
+
+The player entity is normally `ENTITIES[0]` but there is no hardcoded assumption about its index beyond being initialized with `ENTITY_TYPE_PLAYER`.
+
+---
+
+## NPC (`npc.h` / `npc.c`)
+
+`npcInit()`, `npcMovement()`, and `npcInteract()` provide the NPC type callbacks. Currently stubs; movement does nothing, interact returns false.

+# RPG Layer
+
+The RPG layer lives in `src/dusk/rpg/` and is the game-logic tier above the engine. It is initialized and ticked by `engine.c` via `rpgInit` / `rpgUpdate` / `rpgDispose`. The `rpg_t` struct is currently a stub; all meaningful state lives in the subsystems below.
+
+## Contents
+
+- [world.md](world.md) — scene manager, overworld map, chunks, tiles, coordinate system, camera
+- [entity.md](entity.md) — entity pool, types, direction, animation, interaction, player, NPC
+- [cutscene.md](cutscene.md) — cutscene system, item types, mode control, textbox
+- [story.md](story.md) — story flags, items, inventory, backpack, save system
+
+## Scene system
+
+The scene manager (`src/dusk/scene/`) sits above the RPG layer and owns the single active scene. Scenes are identified by `scenetype_t` and registered in `SCENE_TYPES[]` (`scene/scenetype.c`) as `scenecallbacks_t` (init / update / render / dispose).
+
+`scenedata_t` is a union so all scene structs share memory. `sceneSet(type)` defers the transition — the old scene disposes before the new one inits.
+
+Currently the only scene is `SCENE_TYPE_OVERWORLD` → `src/dusk/scene/overworld/sceneoverworld.c`.

+```
+
+The build tool generates:
+- A `storyflag_t` enum (e.g. `STORY_FLAG_TEST`) in the generated header.
+- `STORY_FLAG_VALUES[]` — the runtime array, pre-populated with the `initial` column values.
+
+To add a flag: add a row to the CSV. The build re-runs the Python tool automatically on the next CMake build.
+
+### Access
+
+```c
+storyflagvalue_t v = storyFlagGet(STORY_FLAG_TEST);   // macro: array read
+storyFlagSet(STORY_FLAG_TEST, 1);                      // function: also marks save dirty
+```
+
+`storyFlagGet` is a macro that directly indexes `STORY_FLAG_VALUES[]` — no function call overhead.
+
+---
+
+## Items (`src/dusk/rpg/item/`)
+
+### Item definitions
+
+Items are defined in `src/dusk/rpg/item/item.csv`. The build tool generates `itemid_t` enum values and item metadata. `itemid_t` is a generated `uint8_t` typedef.
+
+### Inventory (`inventory.h`)
+
+`inventory_t` is a generic container backed by a caller-supplied `inventorystack_t` array:
+
+```c
+typedef struct {
+  itemid_t item;
+  uint8_t quantity;        // max ITEM_STACK_QUANTITY_MAX (255)
+} inventorystack_t;
+
+typedef struct {
+  inventorystack_t *storage;
+  uint8_t storageSize;
+} inventory_t;
+```
+
+Key operations:
+
+```c
+inventoryInit(&inv, storageArray, size);
+inventoryAdd(&inv, ITEM_POTION, 3);
+inventoryRemove(&inv, ITEM_POTION);
+inventorySet(&inv, ITEM_POTION, 10);
+inventoryGetCount(&inv, ITEM_POTION);   // returns 0 if not present
+inventoryItemExists(&inv, ITEM_POTION);
+inventoryIsFull(&inv);
+inventorySort(&inv, INVENTORY_SORT_BY_ID, false);
+```
+
+`inventory_t` itself holds no data — the backing array is always external. This avoids fixed-size struct limits and lets different inventories (backpack, shop, chest) share the same logic.
+
+### Backpack (`backpack.h`)
+
+The player's inventory is the global `BACKPACK` instance:
+
+```c
+extern inventorystack_t BACKPACK_STORAGE[BACKPACK_STORAGE_SIZE_MAX];  // 20 slots
+extern inventory_t BACKPACK;
+
+backpackInit();   // wires BACKPACK_STORAGE into BACKPACK
+```
+
+---
+
+## Save system (`src/dusk/save/`)
+
+The save system is stubbed out — it exists and compiles but is commented out of engine init (`engine.c`). What follows describes the design as implemented.
+
+### Slots
+
+`save_t SAVE` holds `SAVE_FILE_COUNT_MAX` slots:
+
+```c
+typedef struct {
+  savefile_t files[SAVE_FILE_COUNT_MAX];
+  saveplatform_t platform;   // platform-specific state (paths, card handles)
+} save_t;
+```
+
+### Streams
+
+`savestream_t` (`save/savestream.h`) is a raw byte cursor used to serialize/deserialize `savefile_t`. Platform backends in `src/dusk{platform}/save/` implement the actual I/O:
+- Linux: filesystem files in a save directory.
+- GameCube/Wii: memory card via libogc.
+
+### API
+
+```c
+saveInit();
+saveLoad(slot);     // reads platform storage → savefile_t
+saveWrite(slot);    // writes savefile_t → platform storage
+saveDelete(slot);
+saveExists(slot);   // bool
+saveGet(slot);      // returns savefile_t *
+saveDispose();
+```
+
+---
+
+## Locale / i18n (`src/dusk/locale/`)
+
+Translations are loaded from `.po` files in `assets/locale/` (e.g. `en_US.po`). `localemanager.c` manages the active locale and exposes a key→string lookup. `assetlocaleloader.c` parses the PO format via the asset system.
+
+All player-visible strings must go through the locale system rather than being hardcoded. The locale is loaded asynchronously via the asset system so it is available before the first scene renders.

+# World
+
+Source: `src/dusk/rpg/overworld/`
+
+---
+
+## Coordinate system
+
+Three nested coordinate spaces, each defined in `worldpos.h`:
+
+| Type | Description | Unit |
+|---|---|---|
+| `worldpos_t` | Tile-level absolute position `{x, y, z}` | `worldunit_t` (int16) |
+| `chunkpos_t` | Chunk-grid position `{x, y, z}` | `chunkunit_t` (int16) |
+| `fixed_t[3]` | Smooth sub-tile position used by entities | Q24.8 fixed-point |
+
+One chunk = `CHUNK_WIDTH × CHUNK_HEIGHT × CHUNK_DEPTH` tiles (16 × 16 × 8).
+The loaded world window = `MAP_CHUNK_WIDTH × MAP_CHUNK_HEIGHT × MAP_CHUNK_DEPTH` chunks (5 × 5 × 3).
+
+Conversion helpers (all in `worldpos.c`):
+
+```c
+worldPosToChunkPos(&worldPos, &chunkPos);   // tile → chunk grid
+chunkPosToWorldPos(&chunkPos, &worldPos);   // chunk grid → tile origin
+worldPosToChunkTileIndex(&worldPos);        // tile → index within its chunk
+chunkPosToIndex(&chunkPos);                 // chunk grid → linear index in MAP.chunks[]
+worldPosToFixed(&worldPos, fixedOut);       // tile → entity fixed position
+fixedToWorldPos(fixedPos);                  // entity fixed → tile (truncates frac)
+```
+
+---
+
+## Tiles
+
+Defined in `tile.h` as a plain `tile_t` enum:
+
+```
+TILE_SHAPE_NULL    — empty / unloaded
+TILE_SHAPE_GROUND  — solid flat tile
+TILE_SHAPE_RAMP_*  — directional ramps (N/S/E/W + diagonals NE/NW/SE/SW)
+```
+
+Key predicates:
+- `tileIsWalkable(tile)` — true for GROUND and all ramp shapes.
+- `tileIsRamp(tile)` — true only for ramp shapes.
+
+Entity walk code (`entity.c`) checks both the current tile and the target tile to decide whether the entity steps forward flat, raises one Z level (walking up a ramp), or falls one Z level (stepping onto a downward ramp from above).
+
+---
+
+## Chunks
+
+`chunk_t` (`chunk.h`) holds:
+- `position` — its `chunkpos_t` in the world grid
+- `tiles[CHUNK_TILE_COUNT]` — flat array of `tile_t`, indexed by `chunkGetTileIndex()`
+- `vertices[CHUNK_VERTEX_COUNT]` / `mesh` — pre-baked mesh uploaded to GPU on load
+- `entities[CHUNK_ENTITY_COUNT_MAX]` — indices into `ENTITIES[]` currently in this chunk (sentinel `0xFF`)
+- `testColor` — temporary debug color (checkerboard), will be replaced by real tileset data
+
+Tile layout within a chunk is `z * W*H + y * W + x` (Z-major, row-major in XY).
+
+---
+
+## Map
+
+`map_t MAP` (`map.h`) is the single global map instance.
+
+```c
+chunk_t chunks[MAP_CHUNK_COUNT];         // flat storage — index is NOT world position
+chunk_t *chunkOrder[MAP_CHUNK_COUNT];    // draw-order sorted pointers into chunks[]
+chunkpos_t chunkPosition;               // world-grid origin of the loaded window
+bool_t loaded;
+```
+
+### Load / unload
+
+`mapInit()` allocates chunk meshes and performs the initial load of all chunks in the starting window.
+
+`mapPositionSet(newPos)` shifts the window:
+1. Determines which of the `MAP_CHUNK_COUNT` slots remain within the new window vs. fall outside it.
+2. Calls `mapChunkUnload()` on every chunk that falls outside (nulls its entity slots, zeroes `vertCount`).
+3. Reuses freed slots for newly-in-range chunks; calls `mapChunkLoad()` on each.
+4. Rebuilds `chunkOrder[]` in XYZ order for the new position.
+
+### Chunk load (current stub)
+
+`mapChunkLoad()` currently:
+- Fills all tiles with `TILE_SHAPE_GROUND`
+- Assigns a checkerboard debug color based on chunk XY parity
+- Bakes a flat sprite-batch quad mesh for the z=0 layer and uploads it via `meshFlush()`
+- Skips mesh generation for z > 0 chunks (they're empty)
+
+### Tile lookup
+
+```c
+tile_t mapGetTile(const worldpos_t position);
+```
+
+Converts `position` to its chunk, looks up the chunk in `chunkOrder`, then indexes into `chunk->tiles[]`. Returns `TILE_SHAPE_NULL` for any out-of-bounds position or when the map is not loaded.
+
+---
+
+## Camera
+
+`rpgcamera_t RPG_CAMERA` (`rpgcamera.h`) has two modes:
+
+```c
+RPG_CAMERA_MODE_FREE            // free worldpos; camera.free holds the position
+RPG_CAMERA_MODE_FOLLOW_ENTITY   // tracks ENTITIES[followEntityId]
+```
+
+`rpgCameraGetPosition()` returns the active world tile position in either mode.
+
+The scene renderer (`sceneoverworld.c`) uses `rpgCameraGetPosition()` to build the `glm_lookat` view matrix. When following an entity, it sub-tile interpolates between `entity->lastPosition` and `entity->position` using `entity->animTime / ENTITY_ANIM_WALK_DURATION` to smooth movement.

+# Save & Locale
+
+---
+
+## Save system (`src/dusk/save/`)
+
+Slot-based persistent storage. Currently disabled in engine init (commented out in `engine.c`) — the system is fully implemented but not yet wired up.
+
+### Slots
+
+Up to `SAVE_FILE_COUNT_MAX` (3) save slots. The global `SAVE` holds all slots:
+
+```c
+saveInit();
+saveExists(slot);          // bool_t — check before load
+saveLoad(slot);            // read from platform storage → SAVE.files[slot]
+saveWrite(slot);           // write SAVE.files[slot] → platform storage
+saveDelete(slot);
+savefile_t *f = saveGet(slot);
+saveDispose();
+```
+
+### Save file format
+
+`savefile_t` is the serialized struct stored per slot. Currently minimal:
+
+```c
+typedef struct {
+  char_t header[3];    // "DSK"
+  uint32_t version;    // SAVE_FILE_VERSION = 1
+  bool_t exists;
+} savefile_t;
+```
+
+Extend this struct to add game-specific save data (player position, story flags, etc.).
+
+### Stream serialization (`save/savestream.h`)
+
+`savestream_t` is a cursor used to read/write a save slot's bytes. It CRC32-checksums all data written through it and verifies the checksum on read.
+
+Write a save:
+```c
+savestream_t stream;
+// (platform opens stream for slot)
+saveFileWriteHeader(&stream, SAVE_FILE_HEADER);
+saveFileWriteVersion(&stream, SAVE_FILE_VERSION);
+saveFileWriteBool(&stream, myFlag);
+saveFileWriteInt32(&stream, myInt);
+saveFileWriteString(&stream, myString, sizeof(myString));
+saveStreamFinalizeWriteImpl(&stream);   // writes CRC
+```
+
+Read a save:
+```c
+saveFileReadHeader(&stream, headerBuf);
+saveFileReadVersion(&stream, &version);
+saveFileReadBool(&stream, &myFlag);
+saveFileReadInt32(&stream, &myInt);
+saveFileReadString(&stream, myString, sizeof(myString));
+saveStreamVerifyChecksumImpl(&stream, slot);   // returns error if CRC mismatch
+```
+
+All multi-byte values are stored in little-endian byte order. The `saveFile*` macros are thin wrappers over the `*Impl` functions that integrate `errorChain` — always use the macros.
+
+### Platform backends
+
+Each `src/dusk{platform}/save/` provides `saveplatform_t` (e.g. a file path on Linux, a memory-card handle on GameCube). The stream implementations (`savestream{platform}.c`) do the actual I/O.
+
+---
+
+## Locale / i18n (`src/dusk/locale/`)
+
+Translations are stored as GNU `.po` files in `assets/locale/`. Only `en_US.po` currently exists.
+
+### Loading
+
+`localemanager_t LOCALE` tracks the active locale and its in-progress asset entry:
+
+```c
+localeManagerInit();                         // loads en_US by default
+localeManagerSetLocale(&LOCALE_EN_US);       // switch locale (async load)
+localeManagerDispose();
+```
+
+`LOCALE_EN_US` is a predefined `localeinfo_t` constant (`name = "en-US"`, `file = "locale/en_US.po"`).
+
+### Looking up strings
+
+```c
+char_t buf[128];
+localeManagerGetText("my.key", buf, sizeof(buf), 1, /* format args */ );
+```
+
+The macro handles plural forms and `printf`-style format arguments. Pass plural `1` for singular, any other value for plural.
+
+`assetlocaleloader.c` parses the `.po` format (msgid / msgstr pairs) into a key→string table during the async asset load phase.

+## Naming
+
+| Kind | Convention | Example |
+|---|---|---|
+| Types (struct/union/typedef) | `snake_case_t` | `entity_t`, `worldpos_t` |
+| Struct tags | `struct name_s` | `struct entity_s` |
+| Union tags | `union name_u` | `union texturedata_u` |
+| Enum tags (when typedef'd separately) | `name_enum_t` | `entitytype_enum_t` |
+| Functions | `subsystemVerb` (camelCase, noun-first) | `entityInit`, `mapGetTile` |
+| Macro constants | `UPPER_SNAKE_CASE` | `CHUNK_WIDTH`, `FIXED_ONE` |
+| Function-like macros | `camelCase` (same as functions) | `errorThrow`, `assertNotNull` |
+| Global subsystem instances | `UPPER_SNAKE_CASE` | `ENGINE`, `MAP`, `ENTITIES` |
+| Local variables | `camelCase` | `tileNew`, `spriteCount` |
+| Parameters | `camelCase` | `texture`, `worldPos` |
+
+Subsystem prefix always comes first in function names: `textureInit`, `shaderBind`, `spriteBatchFlush`. The verb describes the action: `Init`, `Update`, `Dispose`, `Get`, `Set`, `Is`, etc.
+
+---
+
+## Typedefs
+
+### Structs
+
+```c
+typedef struct {
+  uint8_t id;
+  entitytype_t type;
+} entity_t;
+```
+
+Use a named tag (`struct entity_s`) only when forward declaration is required:
+
+```c
+typedef struct entity_s {
+  // ...
+} entity_t;
+```
+
+### Unions
+
+```c
+typedef union texturedata_u {
+  struct {
+    uint8_t *indices;
+    palette_t *palette;
+  } paletted;
+  color_t *rgbaColors;
+} texturedata_t;
+```
+
+### Enums
+
+When the enum values need to be a compact integer (common for arrays and flags), declare the enum separately and typedef an integer type:
+
+```c
+typedef enum {
+  ENTITY_TYPE_NULL,
+  ENTITY_TYPE_PLAYER,
+  ENTITY_TYPE_NPC,
+  ENTITY_TYPE_COUNT
+} entitytype_enum_t;
+
+typedef uint8_t entitytype_t;  // actual type used everywhere
+```
+
+Always include `_NULL` as the first value (zero) and `_COUNT` as the last value.
+
+---
+
+## `#define` constants
+
+All-caps, underscores. Wrap multi-token expressions in parentheses:
+
+```c
+#define CHUNK_WIDTH 16
+#define CHUNK_HEIGHT CHUNK_WIDTH
+#define CHUNK_TILE_COUNT (CHUNK_WIDTH * CHUNK_HEIGHT * CHUNK_DEPTH)
+```
+
+Multi-line macros: backslash continuation, body indented 2 spaces, closing line has no backslash:
+
+```c
+#define errorThrow(message, ...) \
+  return errorThrowImpl(\
+    &ERROR_STATE, ERROR_NOT_OK, __FILE__, __func__, __LINE__, (message), \
+    ##__VA_ARGS__ \
+  )
+```
+
+---
+
+## `const` usage
+
+Mark every pointer and value parameter `const` unless the function modifies it:
+
+```c
+void entityTurn(entity_t *entity, const entitydir_t direction);
+errorret_t textureInit(texture_t *texture, const int32_t width, ...);
+```
+
+`entity_t *entity` is non-const because the function writes to it; `direction` is const because it is read-only.
+
+---
+
+## `void` in no-argument functions
+
+Use `(void)` in definitions and declarations of zero-parameter functions:
+
+```c
+errorret_t engineUpdate(void);
+errorret_t spriteBatchFlush(void);
+```
+
+---
+
+## Unused parameters
+
+Do **not** use `(void)param;` casts to suppress unused-parameter warnings. They are
+redundant noise. If a callback signature is fixed by a function-pointer type and the
+parameter is genuinely unused, just leave it — do not suppress:
+
+```c
+// correct — parameter unused, no cast
+errorret_t sceneTestUpdate(scenedata_t *data) {
+  errorOk();
+}
+
+// wrong
+errorret_t sceneTestUpdate(scenedata_t *data) {
+  (void)data;
+  errorOk();
+}
+```
+
+---
+
+## Global subsystem state
+
+Each subsystem exposes a single global instance declared `extern` in the header and defined (once) in the `.c` file:
+
+```c
+// entity.h
+extern entity_t ENTITIES[ENTITY_COUNT];
+
+// entity.c
+entity_t ENTITIES[ENTITY_COUNT];
+```
+
+Never define a subsystem global as `static` in a header.
+
+---
+
+## Assertions
+
+Place assertions at the very top of a function, before any logic:
+
+```c
+void entityInit(entity_t *entity, const entitytype_t type) {
+  assertNotNull(entity, "Entity pointer cannot be NULL");
+  assertTrue(type < ENTITY_TYPE_COUNT, "Invalid entity type");
+  // ... actual logic
+}
+```
+
+Available assertion macros (from `assert/assert.h`):
+- `assertNotNull(ptr, msg)`
+- `assertNull(ptr, msg)`
+- `assertTrue(expr, msg)`
+- `assertFalse(expr, msg)`
+- `assertUnreachable(msg)`
+- `assertStringEqual(a, b, msg)`
+- `assertIsMainThread(msg)` / `assertNotMainThread(msg)`
+
+---
+
+## Error handling style
+
+Functions that can fail return `errorret_t`. Three patterns:
+
+```c
+// Propagate a child call's failure and return from this function:
+errorChain(someCall());
+
+// Return success:
+errorOk();
+
+// Return failure:
+errorThrow("Descriptive message %s", variable);
+```
+
+`errorChain` is used inline — do not capture the result first:
+```c
+errorChain(textureInitPlatform(texture, width, height, format, data));  // correct
+errorret_t r = textureInitPlatform(...); errorChain(r);                 // wrong
+```
+
+---
+
+## Struct initialization
+
+Use C99 designated initializers for any struct literal with more than one field:
+
+```c
+static const entitycallback_t ENTITY_CALLBACKS[ENTITY_TYPE_COUNT] = {
+  [ENTITY_TYPE_NULL] = { NULL },
+
+  [ENTITY_TYPE_PLAYER] = {
+    .init = playerInit,
+    .movement = playerInput
+  },
+};
+```
+
+```c
+shadermaterial_t material = {
+  .unlit = {
+    .color = COLOR_WHITE,
+    .texture = NULL
+  }
+};
+```
+
+---
+
+## Fixed-size array iteration
+
+Prefer pointer arithmetic with `do/while` over index loops for iterating through fixed global arrays:
+
+```c
+entity_t *ent = ENTITIES;
+do {
+  if(ent->type == ENTITY_TYPE_NULL) continue;
+  // ...
+} while(++ent, ent < &ENTITIES[ENTITY_COUNT]);
+```
+
+Use `for` loops when an index variable is actually needed.
+
+---
+
+## Comments
+
+Comments explain *why*, not *what*. One short inline comment is fine; multi-line block comments for non-obvious invariants only.
+
+```c
+// Walking up a ramp — only the direction the ramp faces is valid.
+if(tileIsRamp(tileCurrent) && ...) {
+```
+
+Section labels inside long functions are acceptable:
+
+```c
+// Chunks
+{
+  ...
+}
+
+// Entities
+{
+  ...
+}
+```
+
+Doc comments on public functions use Javadoc style with `@param` / `@return`:
+
+```c
+/**
+ * Gets the tile at the given world position.
+ *
+ * @param position The world position.
+ * @return The tile at that position, or TILE_NULL if the chunk is unloaded.
+ */
+tile_t mapGetTile(const worldpos_t position);
+```
+
+---
+
+## Platform-conditional code
+
+Use the `DUSK_*` compile-definition macros set by `cmake/targets/<target>.cmake`:
+
+```c
+#ifdef DUSK_THREAD_PTHREAD
+  #include "thread/thread.h"
+  extern pthread_t ASSERT_MAIN_THREAD_ID;
+#endif
+```
+
+Never use `#ifdef __linux__`, `#ifdef _WIN32`, etc. directly — go through the engine macros.

+## Time (`src/dusk/time/`)
+
+`dusktime_t TIME` tracks fixed and dynamic delta time.
+
+```c
+TIME.delta         // fixed_t: always DUSK_TIME_STEP (16ms default) on fixed-rate platforms
+TIME.time          // fixed_t: total elapsed time in seconds
+```
+
+On platforms with `DUSK_TIME_DYNAMIC` (Linux/SDL2):
+```c
+TIME.dynamicDelta  // fixed_t: actual time since last frame
+TIME.dynamicTime   // fixed_t: total elapsed (dynamic)
+TIME.dynamicUpdate // bool_t: true when a real tick occurred
+```
+
+Call `timeUpdate()` once per frame (before input/logic). `timeGetEpoch()` returns the current wall-clock time as a `dusktimeepoch_t`.
+
+### Epoch time (`time/timeepoch.h`)
+
+`dusktimeepoch_t` stores a Unix timestamp (double) with timezone offset. Utilities:
+
+```c
+dusktimeepoch_t e = timeGetEpoch();
+timeEpochGetHours(e)      // 0–23
+timeEpochGetMinutes(e)    // 0–59
+timeEpochGetSeconds(e)    // 0–59
+timeEpochGetDayOfMonth(e) // 0–30
+timeEpochGetMonth(e)      // 0–11
+timeEpochGetYear(e)
+
+// Format: %Y year, %m month, %d day, %H hour, %M minute, %S second
+timeEpochFormat(e, "%Y-%m-%d %H:%M:%S", buf, sizeof(buf));
+
+// Compare: returns -1, 0, 1
+timeEpochCompare(a, b);
+
+// Timezone shift:
+dusktimeepoch_t local = timeEpochSwitchTimeZone(e, offsetHours);
+```
+
+---
+
+## Thread (`src/dusk/thread/`)
+
+Currently only the pthread backend (`DUSK_THREAD_PTHREAD`) exists. Thread objects are `thread_t` — used primarily by the asset loader.
+
+```c
+threadInit(&thread, myCallback);   // myCallback: void (*)(thread_t *)
+threadStart(&thread);              // blocks until thread is RUNNING
+threadStop(&thread);               // requests stop, blocks until STOPPED
+
+// Inside the thread callback:
+while(!threadShouldStop(&thread)) { /* work */ }
+```
+
+State flow: `STOPPED → STARTING → RUNNING → (STOP_REQUESTED) → STOPPED`.
+
+### Mutex (`thread/threadmutex.h`)
+
+```c
+threadMutexInit(&lock);
+threadMutexLock(&lock);
+threadMutexUnlock(&lock);
+threadMutexTryLock(&lock);       // non-blocking; returns false if already held
+threadMutexWaitLock(&lock);      // release lock and sleep until signalled
+threadMutexSignal(&lock);        // wake a thread waiting on this mutex
+threadMutexDispose(&lock);
+```
+
+### Thread-local storage
+
+`THREAD_LOCAL` expands to `__thread` (GCC) on pthread platforms. Used for the per-thread error state (`ERROR_STATE` in `error/error.h`).
+
+---
+
+## Event (`src/dusk/event/`)
+
+A fixed-capacity multicast callback list.
+
+```c
+// Declare backing arrays (choose a size):
+eventcallback_t cbs[4];
+void *users[4];
+event_t myEvent;
+eventInit(&myEvent, cbs, users, 4);
+
+eventSubscribe(&myEvent, myCallback, myUser);
+eventUnsubscribe(&myEvent, myCallback);
+eventInvoke(&myEvent, params);   // calls all subscribers; params passed as-is
+```
+
+Callback signature: `void cb(void *params, void *user)`.
+
+`event_t` does not own its callback/user arrays. Always declare them alongside the event in the same struct or as static arrays.
+
+---
+
+## Console (`src/dusk/console/`)
+
+`CONSOLE` is a scrolling in-game terminal for debug output. On POSIX platforms (`DUSK_CONSOLE_POSIX`) it also polls stdin in a thread so commands can be typed during a running session.
+
+```c
+consolePrint("Value is %d", x);   // printf-style; thread-safe
+consoleDraw();                     // renders visible history lines to screen
+```
+
+Configuration constants (`consoledefs.h`):
+- `CONSOLE_LINE_MAX` — 512 chars per line
+- `CONSOLE_HISTORY_MAX` — 16 lines of scrollback
+- `CONSOLE_EXEC_BUFFER_MAX` — 32 pending exec commands
+
+`CONSOLE.visible` controls whether `consoleDraw()` actually renders anything.
+
+---
+
+## Log (`src/dusk/log/`)
+
+Two simple output functions, implemented per-platform:
+
+```c
+logDebug("format %s", arg);   // debug output (stdout on Linux, debug channel on consoles)
+logError("format %s", arg);   // error output; may pause execution on some platforms
+```
+
+These go directly to the platform's native output and are not buffered by the console history.
+
+---
+
+## System / Platform (`src/dusk/system/`)
+
+`systemInit()` runs platform-specific startup (e.g. Wii PAD init, PSP kernel setup). Must be the first call in `engineInit()`.
+
+```c
+systemplatform_t p = systemGetPlatform();   // SYSTEM_PLATFORM_LINUX, _PSP, etc.
+systemdialogtype_t d = systemGetActiveDialogType();
+// SYSTEM_DIALOG_TYPE_NONE / RENDER_BLOCKING / TICK_BLOCKING
+```
+
+The full platform list is defined via X-macro in `system/systemplatformlist.h`:
+
+| Constant | Value |
+|---|---|
+| `SYSTEM_PLATFORM_LINUX` | 0 |
+| `SYSTEM_PLATFORM_KNULLI` | 1 |
+| `SYSTEM_PLATFORM_PSP` | 2 |
+| `SYSTEM_PLATFORM_GAMECUBE` | 3 |
+| `SYSTEM_PLATFORM_WII` | 4 |
+
+---
+
+## Network (`src/dusk/network/`)
+
+`network_t NETWORK` manages platform connection state. The engine calls `networkInit` / `networkUpdate` / `networkDispose`; game code uses the request API:
+
+```c
+networkRequestConnection(onConnected, onFailed, onDisconnect, user);
+networkRequestDisconnection(onComplete, user);
+networkIsConnected();   // bool_t
+```
+
+State machine: `DISCONNECTED → CONNECTING → CONNECTED → DISCONNECTING → DISCONNECTED`.
+
+Network address info (after connection):
+```c
+networkinfo_t info = networkGetInfo();
+// info.type = NETWORK_TYPE_IPV4 / IPV6
+// info.ipv4.ip[4] or info.ipv6.ip[16]
+```
+
+Platform backends implement `networkPlatformInit/Update/Dispose/IsConnected`. Currently only Linux (socket-based) and PSP/Vita are implemented.

+# UI System
+
+Source: `src/dusk/ui/`
+
+The UI system is an immediate-mode layer drawn on top of the game scene each frame. Elements register themselves; `uiUpdate()` ticks all elements and `uiRender()` draws them. All coordinates are in screen pixels.
+
+---
+
+## Lifecycle
+
+```
+uiInit() → uiTextboxInit()   // init order matters — textbox depends on display being ready
+uiUpdate()                   // each frame, before rendering
+uiRender()                   // each frame, after scene render
+uiDispose()
+uiTextboxDispose()
+```
+
+---
+
+## Element registration (`ui/uielement.h`)
+
+Elements are stored in `UI_ELEMENTS[]`. Each has a type and a `draw` callback:
+
+```c
+typedef struct {
+  uielementtype_t type;
+  errorret_t (*draw)();
+} uielement_t;
+```
+
+Currently `UI_ELEMENT_TYPE_NATIVE` elements call their `draw` function directly. New debug/HUD elements are registered by adding to this array.
+
+---
+
+## Textbox (`ui/uitextbox.h`)
+
+`UI_TEXTBOX` is the global dialogue box. It word-wraps text, paginates it, and plays a typewriter scroll effect.
+
+```c
+uiTextboxSetText("Long dialogue string...");  // wraps to charsPerLine, paginates
+uiTextboxUpdate();                            // each frame: advance scroll, check input
+uiTextboxDraw();                              // draw box + text
+
+// Pagination:
+uiTextboxPageIsComplete()   // true when all chars of current page are visible
+uiTextboxHasNextPage()
+uiTextboxNextPage()
+
+// Subscibe to page events:
+eventSubscribe(&UI_TEXTBOX.onPageComplete, cb, user);
+eventSubscribe(&UI_TEXTBOX.onLastPage, cb, user);
+```
+
+`UI_TEXTBOX.advanceAction` defaults to the input action that advances dialogue — set it before calling `uiTextboxInit()` if the default doesn't suit.
+
+Layout constants:
+- `UI_TEXTBOX_TEXT_MAX` — 1024 chars
+- `UI_TEXTBOX_LINES_MAX` — 64 lines
+- `UI_TEXTBOX_LINES_PER_PAGE_MAX` — 3 lines visible at once
+- `UI_TEXTBOX_SCROLL_CHARS_PER_TICK` — 1 char per tick (typewriter speed)
+
+The textbox uses `UI_TEXTBOX.frame` (a `uiframe_t`) for its border rendering and `UI_TEXTBOX.font` for text.
+
+---
+
+## UI Frame (`ui/uiframe.h`)
+
+9-slice bordered box rendered with a tileset:
+
+```c
+uiFrameInit(&frame);
+uiFrameDraw(&frame, x, y, width, height);
+uiFrameDispose(&frame);
+```
+
+The tileset is loaded from the asset system during `uiFrameInit()`. The 9 slices are arranged in the tileset grid as: top-left corner, top edge, top-right corner, left edge, fill, right edge, bottom-left, bottom edge, bottom-right.
+
+---
+
+## Loading overlay (`ui/uiloading.h`)
+
+`UI_LOADING` is a full-screen loading indicator with fade-in/fade-out transitions:
+
+```c
+uiLoadingShow(onShownCallback, user);   // fade in; calls callback when fully opaque
+uiLoadingHide(onHiddenCallback, user);  // fade out; calls callback when fully transparent
+uiLoadingUpdate(delta);                 // each frame
+uiLoadingDraw();                        // each frame, over everything
+```
+
+`UI_LOADING_FADE_DURATION` is `FIXED(0.5f)` seconds. Subscribe to `UI_LOADING.onTransitionEnd` for completion events.
+
+---
+
+## Full-box overlay (`ui/uifullbox.h`)
+
+Two global full-screen color overlays: `UI_FULLBOX_UNDER` (drawn before game content) and `UI_FULLBOX_OVER` (drawn after). Used for scene transitions (fade to black, etc.):
+
+```c
+uiFullboxTransition(
+  &UI_FULLBOX_OVER,
+  COLOR_TRANSPARENT, COLOR_BLACK,
+  FIXED(0.5f),
+  EASING_IN_OUT_CUBIC
+);
+eventSubscribe(&UI_FULLBOX_OVER.onTransitionEnd, myCallback, NULL);
+
+uiFullboxUnderDraw();   // draw under layer
+uiFullboxOverDraw();    // draw over layer
+```
+
+---
+
+## FPS counter (`ui/uifps.h`)
+
+`UIFPS` tracks a rolling average FPS. `uiFPSDraw()` renders it in the corner. Currently drawn as part of the debug HUD (not wired to an element slot).
+
+---
+
+## Player position HUD (`ui/uiplayerpos.h`)
+
+`uiplayerpos.c` draws the player's current world tile coordinates. Debug overlay, currently drawn directly in the scene render.

+# Utilities
+
+Source: `src/dusk/util/`
+
+---
+
+## String (`util/string.h`)
+
+**Always use these instead of stdlib equivalents** (`strcmp`, `strcpy`, `sprintf`, etc.).
+
+```c
+stringCopy(dest, src, destSize);           // safe strncpy; always null-terminates
+stringCompare(a, b);                       // -1 / 0 / 1
+stringEquals(a, b);                        // bool_t
+stringCompareInsensitive(a, b);            // case-insensitive -1 / 0 / 1
+stringTrim(str);                           // in-place strip leading/trailing whitespace
+stringFindLastChar(str, c);                // last occurrence pointer or NULL
+stringFormat(dest, destSize, fmt, ...);    // snprintf wrapper; pass NULL dest to get length
+stringFormatVA(dest, destSize, fmt, args); // va_list version
+
+stringIsWhitespace(c);                     // bool_t

+stringToI64(str, &out)   → bool_t
+stringToI16(str, &out)   → bool_t
+stringToU16(str, &out)   → bool_t
+stringToF32(str, &out)   → bool_t
+
+// Suffix checks:
+stringEndsWith(str, suffix)                 → bool_t
+stringEndsWithCaseInsensitive(str, suffix)  → bool_t
+stringIncludesString(haystack, needle)      → bool_t
+```
+
+---
+
+## Memory (`util/memory.h`)
+
+**Always use these instead of `malloc`/`free`/`memcpy`/`memset` directly.**
+
+```c
+memoryAllocate(size)          → void *      // malloc + tracks pointer count
+memoryAlign(alignment, size)  → void *      // aligned malloc
+memoryFree(ptr)                             // free + decrements count
+memoryReallocate(&ptr, size)               // realloc
+memoryResize(&ptr, oldSize, newSize)       // realloc + copy (safe reshape)
+memoryTrack(ptr)                           // track externally-malloc'd pointer
+
+memoryCopy(dest, src, size)                // memcpy
+memoryMove(dest, src, size)                // memmove
+memorySet(dest, value, size)               // memset
+memoryZero(dest, size)                     // memset 0
+memoryCompare(a, b, size)     → int_t      // memcmp
+
+// Useful for uploading vertex data with different source/dest layouts:
+memoryCopyInterleaved(dest, destStride, src, srcStride, elementSize, count);
+memoryCopyRangeSafe(dest, start, end, sizeMax);  // copy with bounds check
+
+memoryGetAllocatedCount()     → size_t     // current malloc'd block count
+```
+
+---
+
+## Math (`util/math.h`)
+
+```c
+mathNextPowTwo(value)    → uint32_t   // next power of two >= value
+mathMax(a, b)                         // macro
+mathMin(a, b)                         // macro
+mathClamp(x, lower, upper)            // macro
+mathAbs(amt)                          // macro
+mathModFloat(x, y)       → float_t    // always non-negative modulo
+mathLerp(a, b, t)        → float_t    // linear interpolation (floats)
+```
+
+For fixed-point lerp use `fixedLerp(a, b, t)` from `util/fixed.h`.
+
+`MATH_PI` is defined as `M_PI`.
+
+---
+
+## Fixed-point (`util/fixed.h`)
+
+Q24.8 format: 24-bit integer part, 8-bit fractional part (`int32_t`). See [architecture.md](architecture.md#fixed-point-math) for the full API.
+
+Quick reference:
+```c
+FIXED(1.5f)               // compile-time literal
+fixedFromI32(3)           // runtime int → fixed
+fixedToFloat(f)           // fixed → float (only for GL/platform APIs)
+fixedMul(a, b)            // multiplication (not just addition)
+fixedDiv(a, b)            // division
+fixedLerp(a, b, t)        // lerp where t ∈ [0, FIXED_ONE]
+```
+
+---
+
+## Array (`util/array.h`)
+
+```c
+arrayReverse(array, count, size);   // in-place reverse; size = sizeof(element)
+```
+
+---
+
+## Sort (`util/sort.h`)
+
+```c
+sortQuick(array, count, size, compare);   // quicksort
+sortBubble(array, count, size, compare);  // bubble sort (small arrays)
+sort(array, count, size, compare);        // macro alias for sortQuick
+
+// Convenience uint8_t sorter:
+sortArrayU8(array, count);
+int sortArrayU8Compare(const void *a, const void *b);   // comparator
+```
+
+`sortcompare_t` matches `qsort` comparator signature: `int (*)(const void *, const void *)`.
+
+---
+
+## Reference counting (`util/ref.h`)
+
+```c
+refInit(&ref, dataPtr, onLock, onUnlock, onAllUnlocked);
+refLock(&ref);              // increments count, calls onLock
+bool_t hit_zero = refUnlock(&ref);   // decrements; calls onAllUnlocked when 0
+```
+
+Used internally by the asset entry system to track how many callers hold a reference to a loaded asset entry.
+
+---
+
+## CRC32 (`util/crypt.h`)
+
+```c
+// One-shot:
+uint32_t crc = cryptCRC32(data, size);
+
+// Streaming:
+uint32_t acc = cryptCRC32Begin();
+cryptCRC32Update(&acc, chunk1, len1);
+cryptCRC32Update(&acc, chunk2, len2);
+uint32_t final = cryptCRC32End(acc);
+```
+
+Used by the save stream to checksum save files.
+
+---
+
+## Endian (`util/endian.h`)
+
+All serialized data (save files, asset headers) is little-endian. Convert to/from host byte order:
+
+```c
+uint32_t val = endianLittleToHost32(rawU32);
+uint16_t val = endianLittleToHost16(rawU16);
+float_t  val = endianLittleToHostFloat(rawFloat);
+```
+
+`isHostLittleEndian()` returns a bool at runtime. The compile-time defines `DUSK_PLATFORM_ENDIAN_LITTLE` / `DUSK_PLATFORM_ENDIAN_BIG` are set by `cmake/targets/<target>.cmake`.

-
+cmake --build build-<target> -- -j$(nproc)
-## C conventions
-
-### Types
-Always use the project-defined aliases instead of bare C primitives:
-
-| Use       | Not          |
-|-----------|--------------|
-| `bool_t`  | `bool`       |
-| `int_t`   | `int`        |
-| `float_t` | `float`      |
-| `char_t`  | `char`       |
-
-Use `uint8_t`, `uint16_t`, `int32_t`, etc. for fixed-width integers.
-All struct and enum types end in `_t` (`animation_t`, `errorret_t`, …).
-
-### Naming
-- **Functions** — snake_case, prefixed with their module:
-  `assetLock()`, `entityPositionInit()`, `moduleAssetBatchCtor()`
-- **Struct fields** — camelCase: `keyframeCount`, `localPosition`
-- **Macros / constants** — UPPER_SNAKE_CASE:
-  `ENTITY_ID_INVALID`, `ERROR_OK`, `COMPONENT_TYPE_COUNT`
-- **Files** — snake_case matching the primary type: `entityposition.c`,
-  `moduleassetbatch.c`
-
-### Header files (`.h`)
-- Use `#pragma once` — no include guards.
-- Declare every public function, `#define`, and `extern` global.
-- Write a JSDoc block (`/** … */`) above every declaration explaining
-  purpose, `@param`s, and `@returns`.
-- Only include headers that the `.h` file itself strictly requires for
-  the types it exposes. Move everything else to the `.c` file.
-  Do not use forward declarations as a workaround — use the real
-  include in the `.c` file instead.
-
-### Implementation files (`.c`)
-- Contain function bodies only; no declarations.
-- Pull in whatever additional includes the implementation needs.
-- Do not use `static` or `inline` on **functions**. Every function,
-  including internal helpers, must be declared in the matching `.h` and
-  defined in the `.c` file. Internal helpers belong near the bottom of
-  the `.c` file, not at the top with a `static` qualifier.
-  `static` and `inline` on functions are only appropriate when the
-  function body is written directly inside a `.h` file.
-  `static` on **variables** (file-scope state) is fine and expected.
-
-### Formatting
-- Hard-wrap all lines at **80 characters**.
-
-### Error handling
-Return `errorret_t` from fallible functions. Use these macros:
-
-```c
-errorOk();                    // return success
-errorThrow("msg %d", val);    // return failure with message
-errorChain(someCall());       // propagate failure, continue on success
-errorIsOk(ret) / errorIsNotOk(ret)  // test a result
-errorCatch(ret);              // handle + free an error
 ```
 
-Never return raw error codes or use `errno` for in-engine errors.
+## Tests
 
-### Memory
+```bash
-Use the project allocator — never raw `malloc`/`free`:
+./scripts/test-linux.sh           # builds and runs all tests
 
-```c
+# Manually run a single test binary after building:
-memoryAllocate(size)          // allocate
+./build-tests/test/<module>/test_<name>
-memoryFree(ptr)               // free
-memoryZero(dest, size)        // zero a block
-memoryCopy(dest, src, size)   // copy
 ```
 
-### Asserts
+Tests use [cmocka](https://cmocka.org/) and are only compiled when `DUSK_BUILD_TESTS=ON`. Test sources live under `test/`.
-Prefer specific assert macros over bare `assert()`:
 
-```c
+## Key conventions
-assertNotNull(ptr, "msg");
-assertTrue(cond, "msg");
-assertFalse(cond, "msg");
-assertUnreachable("msg");
-assertIsMainThread("msg");
-```
 
----
+- Use `stringCompare`, `stringCopy`, `stringEquals`, etc. from `util/string.h` — never `strcmp`, `strcpy`, and friends directly.
-
+- All functions that can fail return `errorret_t`. Use `errorThrow(...)`, `errorChain(call())`, and `errorOk()` macros — see `error/error.h`.
-## Build system
+- Positions and game-world values use `fixed_t` (Q24.8 fixed-point, `int32_t`) — not `float`. Use `FIXED(x)` for literals and the `fixedFrom*`/`fixedTo*` helpers in `util/fixed.h`.
-Each subdirectory has its own `CMakeLists.txt` that adds sources with:
-
-```cmake
-target_sources(${DUSK_LIBRARY_TARGET_NAME}
-  PUBLIC
-    myfile.c
-)
-```
-
-Never add source files to the root `CMakeLists.txt` directly.
-
----
-
-## Platform support
-
-### Targets
-Set `DUSK_TARGET_SYSTEM` at CMake configure time to select a platform:
-
-| `DUSK_TARGET_SYSTEM` | Macro defined     | Platform         |
-|----------------------|-------------------|------------------|
-| `linux`              | `DUSK_LINUX`      | Linux desktop    |
-| `knulli`             | `DUSK_KNULLI`     | Knulli (handheld)|
-| `psp`                | `DUSK_PSP`        | Sony PSP         |
-| `vita`               | `DUSK_VITA`       | PlayStation Vita |
-| `gamecube`           | `DUSK_GAMECUBE`   | Nintendo GameCube|
-| `wii`                | `DUSK_WII`        | Nintendo Wii     |
-
-### Layer structure
-```
-src/dusk/          core, platform-agnostic game logic
-src/duskgl/        OpenGL abstraction (Linux, Knulli, PSP, Vita)
-src/dusksdl2/      SDL2 window + input (Linux, Knulli, PSP, Vita)
-src/dusklinux/     Linux + Knulli platform impl
-src/duskpsp/       PSP platform impl
-src/duskvita/      Vita platform impl
-src/duskdolphin/   GameCube / Wii platform impl (no SDL2/OpenGL)
-```
-
-Dolphin is the only target that bypasses SDL2 and OpenGL entirely —
-it uses native GameCube/Wii rendering and input APIs.
-
-### Platform guards
-Use the compile-time macros for platform-specific code:
-
-```c

-#elif defined(DUSK_GAMECUBE) || defined(DUSK_WII)
-  // GameCube / Wii path

-
-Additional capability macros set per-target:
-`DUSK_SDL2`, `DUSK_OPENGL`, `DUSK_OPENGL_ES`, `DUSK_OPENGL_LEGACY`,
-`DUSK_INPUT_GAMEPAD`, `DUSK_INPUT_KEYBOARD`, `DUSK_INPUT_POINTER`,
-`DUSK_PLATFORM_ENDIAN_BIG` / `DUSK_PLATFORM_ENDIAN_LITTLE`.
-
-### Abstraction pattern
-Platform-specific implementations are wired in via `#define` macros in
-each platform's `displayplatform.h` / `inputplatform.h` etc., which
-the core calls through. Functions that a platform does not support are
-simply left undefined — the core guards calls with `#ifdef`.
-
-### Adding platform-specific code
-- Put it under `src/dusk<platform>/` in the matching subsystem folder.
-- Gate any core call-site with the appropriate `#ifdef DUSK_<PLATFORM>`
-  or capability macro.
-- Keep the `src/dusk/` core free of platform ifdefs — delegate through
-  the platform header macros instead.

-## Adding a new asset loader type
-1. Add an enum value to `assetloadertype_t` (before `_COUNT`) in
-   `src/dusk/asset/loader/assetloader.h`.
-2. Add fields to the input/loading/output unions in `assetloader.h`.
-3. Implement `assetXxxLoaderSync`, `assetXxxLoaderAsync`, and
-   `assetXxxDispose` in a new `src/dusk/asset/loader/xxx/` directory.
-4. Register the three callbacks in `ASSET_LOADER_CALLBACKS[]` in
-   `src/dusk/asset/loader/assetloader.c`.
-5. If user-facing, create a JS module (see below) and a `.d.ts` file.
-
----
-
-## Adding a new entity component
-1. Create `src/dusk/entity/component/<category>/entityMyComp.h/.c` with
-   struct `entityMyComp_t`, `entityMyCompInit()`, and optionally
-   `entityMyCompDispose()`.
-2. Add the include to `src/dusk/entity/componentlist.h` header block.
-3. Add a row to `src/dusk/entity/componentlist.h`:
-   ```c
-   X(MYCOMP, entityMyComp_t, myComp, entityMyCompInit, NULL, NULL)
-   ```
-   This auto-generates the enum, union field, and definition entry.
-4. If JS-facing, create the script module and `.d.ts` (see below).
-
----
-
-## Adding a new script (JS) module
-1. Create `src/dusk/script/module/<category>/moduleMyMod.h/.c`.
-   - Declare `extern scriptproto_t MODULE_MYMOD_PROTO;` in the header.
-   - Use `moduleBaseFunction(name)` to define JS-callable functions.
-   - Register props/funcs in `moduleMyModInit()` with
-     `scriptProtoDefineProp` / `scriptProtoDefineFunc` /
-     `scriptProtoDefineStaticFunc`.
-2. `#include` the header in
-   `src/dusk/script/module/modulelist.c` and call
-   `moduleMyModInit()` in `moduleListInit()` (and `Dispose` in
-   `moduleListDispose()`).
-3. For component modules also register in
-   `src/dusk/script/module/entity/component/modulecomponentlist.c`
-   so `entity.add()` returns the typed wrapper.
-4. Create `types/<category>/mymod.d.ts` and add a
-   `/// <reference path="..." />` line to `types/index.d.ts`.
-
----
-
-## Script module type declarations
-Whenever a `src/dusk/script/module/**/*.c` file is created or modified,
-check whether the corresponding `types/**/*.d.ts` needs updating and
-apply any changes before finishing the task.
-
----
-
-## JavaScript (asset scripts)
-- Use `var` for module-level state; `const` for values that never
-  change.
-- Always use semicolons.
-- Scene objects are plain objects (`var scene = {}`) with assigned
-  methods.
-- Export via `module.exports = scene`.
-- Async scene init should use `async function` and `await`.
-
----
 
 ## Coding style
 
-### ASCII only
+See [`.claude/style.md`](.claude/style.md) for the full style guide: indentation, line length, naming, typedefs, defines, include order, `const` usage, assertion placement, error handling, struct initialization, and platform conditionals.
-Source files (`.c`, `.h`, `.js`) must contain only ASCII characters (U+0000–U+007F).
-Non-ASCII characters are banned even in comments and string literals.
-Use ASCII-only substitutes instead:
-- `--` or `-` instead of `—` (em dash)
-- `->` instead of `→` (arrow)
-- `x` or `*` instead of `×` (multiplication)
 
-Only non-script asset files (e.g. `.po` locale files) may contain non-ASCII text.

-```
-
-Spaces around all binary operators and after every comma:
-
-```c
-pos->flags |= ENTITY_POSITION_FLAG_WORLD_DIRTY;
-(size_t)end - (size_t)start
-foo(a, b, c)
-```
-
-### Braces
-Opening brace on the **same line** as the statement (K&R style) for all
-constructs — functions, `if`, `else`, `for`, `while`, `switch`:
-
-```c
-void assetEntryLock(assetentry_t *entry) {
-  ...
-}
-
-if(dirty) {
-  ...
-} else {
-  ...
-}
-```
-
-### Guard returns
-Short guards go on one line with no braces:
-
-```c
-if(!ptr) return;
-if(!b || !b->batch) return jerry_undefined();
-if(!(flags & DIRTY)) return;
-```
-
-### Blank lines
-- One blank line between functions; no blank line at the start or end of
-  a function body.
-- One blank line between logical blocks inside a function body.
-- No trailing blank lines at the end of a file.
-
-### Pointer placement
-`*` is attached to the variable name, not the type:
-
-```c
-assetentry_t *entry
-const char_t *name
-void *ptr
-uint8_t *d = (uint8_t *)dest;
-```
-
-### Casts
-Space between cast and operand:
-
-```c
-(assetbatch_t *)user
-(uint8_t *)dest
-(textureformat_t)v
-```
-
-### Return
-No parentheses around the return value:
-
-```c
-return ptr;
-return MEMORY_POINTERS_IN_USE;
-```
-
-### switch / case
-`case` indented 2 spaces from `switch`; body indented 2 more from `case`:
-
-```c
-switch(type) {
-  case ASSET_LOADER_TYPE_TEXTURE:
-    descs[i].input.texture = (textureformat_t)v;
-    break;
-  default:
-    break;
-}
-```
-
-### Multi-line function signatures
-When parameters don't fit on one line, put each on its own line indented
-2 spaces; the closing `) {` (definition) or `);` (declaration) goes on
-its own line at column 0:
-
-```c
-void assetEntryInit(
-  assetentry_t *entry,
-  const char_t *name,
-  const assetloadertype_t type,
-  assetloaderinput_t *input
-) {
-
-errorret_t memoryCompare(
-  const void *a,
-  const void *b,
-  const size_t size
-);
-```
-
-### Structs and enums
-Anonymous inner struct or enum with a `typedef`, `_t` suffix, closing
-brace and name on the same line:
-
-```c
-typedef struct {
-  errorcode_t code;
-  char_t *message;
-} errorstate_t;
-
-typedef enum {
-  ASSET_LOADER_TYPE_NULL,
-  ASSET_LOADER_TYPE_COUNT
-} assetloadertype_t;
-```
-
-### Designated initialisers
-Spaces inside braces; `.field = value`:
-
-```c
-jsassetentry_t e = { .entry = entry };
-assetbatchloadedpend_t init = { .batch = batch };
-```
-
-### Ternary operator
-Spaces around `?` and `:`:
-
-```c
-const float val = psx > 0.0f ? pt[0][0] / psx : 0.0f;
-```
-
-### const placement
-`const` before the type, `*` attached to the variable:
-
-```c
-const char_t *name
-const void *src
-const size_t size
-```
-
-### Comments in `.c` files
-- Do not use section dividers (`/* ---- ... ---- */`). Just let the
-  functions follow one another with a single blank line between them.
-- Multi-line explanatory comments inside function bodies use `//` lines:
-  ```c
-  // Script modules are freed; orphaned JS wrapper objects now get GC'd
-  // so their finalizers fire before assetDispose() checks ref counts.
-  jerry_heap_gc(JERRY_GC_PRESSURE_HIGH);
-  ```
-- Do not use `/* */` for inline or inline-block comments inside `.c`
-  function bodies.
-
-### Comments in `.h` files
-Every public declaration gets a Javadoc block (`/** … */`) with
-`@param` and `@returns` where relevant. Keep it on the lines immediately
-above the declaration with no blank line in between.
-
----
-
-## Tests
-- Tests live in `test/` mirroring `src/dusk/` structure.
-- Use cmocka; include `dusktest.h`.
-- Test functions: `static void test_something(void **state)`.
-- After each test, assert `memoryGetAllocatedCount() == 0` to catch
-  leaks.
-- Build with `-DDUSK_BUILD_TESTS=ON`.
