-# Dusk — Claude Code rules
-
-## File headers
-Every C, H, and JS file starts with:
-
-```c
-/**
- * Copyright (c) 2026 Dominic Masters
- *
- * This software is released under the MIT License.
- * https://opensource.org/licenses/MIT
- */
-```
-
-JS files use `//` comment style instead.
-
---
-
-## 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.
-
-### Memory
-Use the project allocator — never raw `malloc`/`free`:
-
-```c
-memoryAllocate(size)          // allocate
-memoryFree(ptr)               // free
-memoryZero(dest, size)        // zero a block
-memoryCopy(dest, src, size)   // copy
-```
-
-### Asserts
-Prefer specific assert macros over bare `assert()`:
-
-```c
-assertNotNull(ptr, "msg");
-assertTrue(cond, "msg");
-assertFalse(cond, "msg");
-assertUnreachable("msg");
-assertIsMainThread("msg");
-```
-
---
-
-## Build system
-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
-#ifdef DUSK_PSP
-  // PSP-only path
-#elif defined(DUSK_GAMECUBE) || defined(DUSK_WII)
-  // GameCube / Wii path
-#else
-  // Generic / Linux fallback
-#endif
-```
-
-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
-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.
-
-### Indentation
-2 spaces. No tabs.
-
-### Keyword and operator spacing
-No space between a keyword or function name and its opening parenthesis:
-
-```c
-if(!ptr) return;
-for(uint8_t i = 0; i < count; i++) {
-while(entry->state != DONE) {
-switch(type) {
-sizeof(assetbatch_t)
-memoryZero(ptr, size)
-```
-
-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.
-
---
-
-## Color system
-
-Colors are defined in `src/dusk/display/color.csv` and code-generated
-into a `color.h` header by `tools/color/csv/__main__.py`.
-
-Each row in the CSV has `name,r,g,b,a` with channel values in `[0.0, 1.0]`.
-The script emits four `#define` variants per color plus a bare alias:
-
-```
-COLOR_<NAME>_4B   color4b(r8, g8, b8, a8)   // default alias target
-COLOR_<NAME>_3B   color3b(r8, g8, b8)
-COLOR_<NAME>_3F   color3f(rf, gf, bf)
-COLOR_<NAME>_4F   color4f(rf, gf, bf, af)
-COLOR_<NAME>      COLOR_<NAME>_4B
-```
-
-`color_t` is `color4b_t` (four `uint8_t` channels).
-
-To add a new color, append a row to `color.csv` and rebuild — do not
-hand-edit the generated header.
-
---
-
-## 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`.

+# Scripting
+
+Dusk embeds [JerryScript](https://github.com/jerryscript-project/jerryscript) to
+drive gameplay logic from JavaScript. The engine itself (rendering, physics,
+asset loading, entity storage) is all C; scripts sit on top and manipulate that
+state through a small set of bound objects.
+
+This document covers the JS-facing scripting API. **UI (buttons, sliders,
+menus, etc.) is not exposed to scripts** — it's a separate, C-only API. See
+[UI.md](UI.md) if you're building screens/menus from engine/game C code.
+
+## Lifecycle
+
+On startup, `engineInit()` loads and evaluates `assets/engine.js` as the main
+script, then calls the global `init()` function if one is defined. From then
+on, every engine tick calls (in order):
+
+1. `fixedUpdate()` — once per fixed timestep. Use this for gameplay logic that
+   must be deterministic and independent of display refresh rate (movement,
+   physics-adjacent input handling, etc). Skipped on interpolation/dynamic
+   frames when the build has variable-timestep rendering enabled.
+2. `update()` — once per rendered frame, including interpolation frames. Use
+   this for smooth, purely presentational animation (nothing that needs to be
+   deterministic).
+
+On shutdown, `deinit()` is called once.
+
+All four hooks (`init`, `update`, `fixedUpdate`, `deinit`) are **optional** —
+if a script doesn't define one, the engine simply skips it, no error.
+
+```js
+function update() {
+  cubePosition.rotation.y += TIME.delta * 1.5;
+}
+```
+
+### `async init()` and `include()`
+
+`init` (or any of the other hooks) can be declared `async` and use `await`
+freely, including awaiting `include()` (see below), even though the engine
+calls these functions synchronously from C with no external JS event loop.
+When a hook returns a pending `Promise`, the engine keeps driving the asset
+system and JerryScript's job queue until that promise settles before
+continuing — so by the time e.g. `init()` "returns" from the engine's point of
+view, everything it awaited has actually finished.
+
+```js
+async function init() {
+  Actions = await include("input.js");
+  // ...
+}
+```
+
+If the awaited work throws/rejects, it surfaces as a C-level error.
+
+## Loading other scripts: `include(path)`
+
+```js
+var Actions = await include("input.js");
+```
+
+`include(path)` always returns a `Promise`. The named file is loaded and
+evaluated once no matter how many times (or from how many different scripts)
+you `include()` it — later calls for the same path are handed the same
+in-flight/resolved promise rather than re-running the file.
+
+The included script communicates its result back by assigning to the bare
+global `module`:
+
+```js
+// input.js
+Input.bind("w", INPUT_ACTION_UP);
+// ...
+
+module = {
+  UP: INPUT_ACTION_UP,
+  DOWN: INPUT_ACTION_DOWN,
+  // ...
+};
+```
+
+Whatever `input.js` assigns to `module` becomes the resolved value of the
+promise `include("input.js")` returned — that's what `Actions` ends up being
+in the example above. If the included script throws, the promise rejects
+instead.
+
+## Full example
+
+This is the actual shipped example content (`assets/engine.js` +
+`assets/input.js`):
+
+```js
+// input.js — binds physical buttons to abstract actions, then exports the
+// action constants so other scripts don't need to know raw INPUT_ACTION_* names.
+Input.bind("w", INPUT_ACTION_UP);
+Input.bind("s", INPUT_ACTION_DOWN);
+Input.bind("a", INPUT_ACTION_LEFT);
+Input.bind("d", INPUT_ACTION_RIGHT);
+Input.bind("space", INPUT_ACTION_ACCEPT);
+Input.bind("escape", INPUT_ACTION_RAGEQUIT);
+
+if(typeof INPUT_GAMEPAD !== "undefined") {
+  Input.bind("gamepad_up", INPUT_ACTION_UP);
+  Input.bind("gamepad_down", INPUT_ACTION_DOWN);
+  Input.bind("gamepad_left", INPUT_ACTION_LEFT);
+  Input.bind("gamepad_right", INPUT_ACTION_RIGHT);
+  Input.bind("gamepad_a", INPUT_ACTION_ACCEPT);
+  Input.bind("gamepad_start", INPUT_ACTION_RAGEQUIT);
+}
+
+module = {
+  UP: INPUT_ACTION_UP,
+  DOWN: INPUT_ACTION_DOWN,
+  LEFT: INPUT_ACTION_LEFT,
+  RIGHT: INPUT_ACTION_RIGHT,
+  ACCEPT: INPUT_ACTION_ACCEPT,
+  CANCEL: INPUT_ACTION_CANCEL,
+  RAGEQUIT: INPUT_ACTION_RAGEQUIT
+};
+```
+
+```js
+// engine.js
+var Actions;
+var camera, cameraPosition;
+var cube, cubePosition, cubeRenderable, cubeMesh;

+
+## API reference
+
+### `TIME`
+
+Plain global object, live getters (read fresh engine state every access, not
+snapshotted):
+
+| Property | Type | Description |
+|---|---|---|
+| `TIME.delta` | number | Seconds since the last frame. |
+| `TIME.time` | number | Total elapsed engine time, in seconds. |
+
+### `PLATFORM`
+
+A single global string constant — the compile-time target name, e.g.
+`"linux"`, `"psp"`, `"vita"`, `"dolphin"`. Individual platform builds may
+inject additional platform-specific globals via their own
+`modulePlatformPlatform()` hook; those aren't documented here since they vary
+per target.
+
+### `Input`
+
+Static namespace (not constructible — there's no `new Input()`).
+
+| Method | Description |
+|---|---|
+| `Input.bind(buttonName, action)` | Binds a physical button/key (string, e.g. `"w"`, `"space"`, `"gamepad_up"`) to an abstract `INPUT_ACTION_*` constant. Many buttons can bind to the same action. Throws on an empty/unrecognized button name or invalid action. |
+| `Input.isDown(action)` → boolean | Is the action currently held. |
+| `Input.pressed(action)` → boolean | Action transitioned to down this frame. |
+| `Input.released(action)` → boolean | Action transitioned to up this frame. |
+| `Input.getValue(action)` → number | Current analog value for the action. |
+| `Input.axis(negAction, posAction)` → number | Combined axis value from two opposing actions. |
+| `Input.axis2D(negX, posX, negY, posY)` → `Vec2` | Combined 2D axis from four actions. |
+
+Global `INPUT_ACTION_*` constants (names are stable API; treat the numeric
+values as opaque/build-specific): `INPUT_ACTION_UP`, `INPUT_ACTION_DOWN`,
+`INPUT_ACTION_LEFT`, `INPUT_ACTION_RIGHT`, `INPUT_ACTION_ACCEPT`,
+`INPUT_ACTION_CANCEL`, `INPUT_ACTION_PAUSE`, `INPUT_ACTION_RAGEQUIT`,
+`INPUT_ACTION_CONSOLE`, `INPUT_ACTION_POINTERX`, `INPUT_ACTION_POINTERY`.
+
+Conditionally-defined boolean globals reflecting build capability — only
+present at all if the corresponding input method is compiled in, so
+feature-test with `typeof`, don't assume they exist:
+`INPUT_KEYBOARD`, `INPUT_GAMEPAD`, `INPUT_POINTER`, `INPUT_TOUCH`.
+
+### `Vec2` / `Vec3` / `Vec4`
+
+`new Vec2(x?, y?)`, `new Vec3(x?, y?, z?)`, `new Vec4(x?, y?, z?, w?)` — all
+components optional, default `0`.
+
+Common instance surface across all three: `.dot(other)`, `.length()`,
+`.lengthSq()`, `.normalize()`, `.negate()`, `.add(other)`, `.sub(other)`,
+`.scale(n)`, `.lerp(other, t)` — each of `add`/`sub`/`scale`/`negate`/
+`normalize`/`lerp` returns a **new** vector (non-mutating). `Vec3` additionally
+has `.cross(other)` and `.distance(other)`; `Vec2` has `.distance(other)` too;
+`Vec4` has neither `.cross()` nor `.distance()`.
+
+`Vec4` also has UV aliases over the same four floats: `.u0` (= `.x`), `.v0`
+(= `.y`), `.u1` (= `.z`), `.v1` (= `.w`) — handy for texture-rect style code.
+
+All three have `.x`/`.y`(/`.z`/`.w`) get/set properties and a `.toString()`
+like `"Vec3(1, 2, 3)"`.
+
+**"Vec3Ref" — live references.** Several engine properties (entity
+`position`/`rotation`/`scale`, physics `velocity`, a mesh vertex's `position`)
+return a vector-*like* object instead of a plain `Vec3`. It has the identical
+`.x`/`.y`/`.z` surface, but reads/writes go straight into the underlying
+native buffer — writing `.x` on `entity.position.position` immediately moves
+the entity, no separate assignment needed. Anywhere the API expects a `Vec3`
+argument, a Vec3Ref works too. You never construct one directly; you only
+ever receive them from properties like the ones above.
+
+### `Mat4`
+
+`new Mat4()` — always constructs identity; no other constructor form.
+
+| Member | Description |
+|---|---|
+| `.mul(other)` → `Mat4` | `this * other`. |
+| `.transpose()` → `Mat4` | |
+| `.inverse()` → `Mat4` | |
+| `.determinant()` → number | |
+| `.mulVec3(vec3, w?)` → `Vec3` | `w` defaults to `1.0` (point); pass `0` for a direction. |
+| `.mulVec4(vec4)` → `Vec4` | |
+| `.translate(vec3)` → `Mat4` | Non-mutating — returns a translated copy. |
+| `.scale(vec3)` → `Mat4` | Non-mutating — returns a scaled copy. |
+| `Mat4.identity()` → `Mat4` | Static. |
+| `Mat4.perspective(fov, aspect, near, far)` → `Mat4` | Static, all 4 args required. |
+| `Mat4.lookAt(eye, center, up)` → `Mat4` | Static, all 3 args required `Vec3`s. |
+
+### `Color`
+
+`new Color(r?, g?, b?, a?)` — each an int `0..255`, default `255` (so
+`new Color()` is opaque white). Properties `.r`/`.g`/`.b`/`.a` get/set.
+
+Named factories, each a zero-arg static returning a new opaque `Color`
+(alpha `255` unless noted): `Color.black()`, `Color.white()`, `Color.red()`,
+`Color.green()`, `Color.blue()`, `Color.yellow()`, `Color.cyan()`,
+`Color.magenta()`, `Color.transparent()` (alpha 0), `Color.transparent_white()`
+(alpha 0), `Color.transparent_black()` (alpha 0), `Color.gray()`,
+`Color.light_gray()`, `Color.dark_gray()`, `Color.orange()`, `Color.purple()`,
+`Color.brown()`, `Color.pink()`, `Color.lime()`, `Color.navy()`,
+`Color.teal()`, `Color.cornflower_blue()`.
+
+`Color.rainbow(t?, speed?)` → `Color` — `t` defaults to `TIME.time * 4.0`;
+produces a shifting rainbow color, useful for debug visuals.
+
+### `Mesh`
+
+`new Mesh(vertexCount)` — allocates an uninitialized CPU-side vertex buffer
+(not yet uploaded to the GPU).
+
+| Member | Description |
+|---|---|
+| `.vertices` | Array of vertex wrappers, each with a `.position` (Vec3Ref, writes straight into that vertex). |
+| `.vertexCount` | Read-only. |
+| `.flush()` | Uploads to the GPU. First call initializes the GPU mesh; later calls re-upload the current vertex data — call this after editing `.vertices[i].position`. |
+| `.dispose()` | Frees GPU + CPU resources. |
+
+Static engine-owned singletons (read-only, not something you dispose):
+`Mesh.DEFAULT_CUBE`, `Mesh.DEFAULT_QUAD`, `Mesh.DEFAULT_SPHERE`,
+`Mesh.DEFAULT_PLANE`, `Mesh.DEFAULT_CAPSULE`, `Mesh.DEFAULT_TRIPRISM`.
+
+Static factories (each builds and uploads a brand-new `Mesh`):
+
+| Factory | Notes |
+|---|---|
+| `Mesh.createCube(min?, max?)` | Both `Vec3`, default `(-0.5,-0.5,-0.5)`..`(0.5,0.5,0.5)`. |
+| `Mesh.createQuad(minX?, minY?, maxX?, maxY?)` | Default `-0.5..0.5` both axes; UV fixed `0,0`–`1,1`. |
+| `Mesh.createSphere(radius?, stacks?, sectors?)` | `radius` default `0.5`. |
+| `Mesh.createPlane(width?, height?)` | Defaults `1.0`/`1.0`; XZ-aligned, centered at origin. |
+| `Mesh.createCapsule(radius?, halfHeight?, capRings?, sectors?)` | Defaults `0.5`, `0.5`. |
+| `Mesh.createTriPrism(x0, y0, x1, y1, x2, y2, minZ, maxZ)` | All 8 args required — a triangular cross-section extruded along Z. |
+
+### `Entity` and components
+
+```js
+var e = new Entity();
+var pos = e.add(POSITION);
+```
+
+`new Entity()` allocates an entity. `.id` is the read-only numeric engine ID.
+`.add(TYPE)` adds a component and returns its wrapper (`TYPE` is one of the
+constants below). `.dispose()` removes the entity and all its components.
+
+Component-type constants: `POSITION`, `CAMERA`, `RENDERABLE`, `PHYSICS`,
+`TRIGGER`. Each entity also exposes a lowercase getter that returns the
+existing wrapper if the component is present, or `undefined` if not (it does
+**not** add the component — use `.add()` for that): `entity.position`,
+`entity.camera`, `entity.renderable`, `entity.physics`, `entity.trigger`.
+
+#### `entity.add(POSITION)` → position component
+
+| Member | Description |
+|---|---|
+| `.position` | Vec3Ref. Writing rebuilds the transform automatically. |
+| `.rotation` | Vec3Ref, Euler angles. Same rebuild-on-write behavior. |
+| `.scale` | Vec3Ref. Same rebuild-on-write behavior. |
+| `.parent` | Get/set another position-component wrapper, or `null` to clear parenting. |
+| `.lookAt(target, up?)` | `target` a `Vec3`; `up` defaults to `(0,1,0)`. |
+
+#### `entity.add(CAMERA)` → camera component
+
+| Member | Description |
+|---|---|
+| `.zNear` / `.zFar` | Numbers. |
+| `.fov` | Only meaningful when `projectionType` is `CAMERA_TYPE_PERSPECTIVE`; otherwise get returns `undefined` and set is a no-op. |
+| `.projectionType` | `CAMERA_TYPE_PERSPECTIVE` or `CAMERA_TYPE_ORTHOGRAPHIC`. |
+| `.orthoTop` / `.orthoBottom` / `.orthoLeft` / `.orthoRight` | Only meaningful in orthographic mode, same undefined/no-op rule otherwise. |
+
+#### `entity.add(RENDERABLE)` → renderable component
+

+script today: `Screen`, `SpriteBatch`, `Text`, `Scene`, `Easing`, `Console`,

+in `moduleRegister()` first — see the existing entries there and the modules
+under `src/dusk/script/module/` for the pattern to follow.

+# UI
+
+Dusk's UI system (buttons, checkboxes, sliders, dropdowns, tabs, menus, focus
+navigation) is a **C-only API**. It is not exposed to JerryScript — see
+[SCRIPTING.md](SCRIPTING.md) for what scripts *can* touch. If you need a
+script to open/react to a menu, wire it through a C callback or a game-side
+flag scripts can poll; there's no bridge for this today.
+
+## Mental model
+
+There is no retained-mode UI tree, no automatic dispatch, no scissor/clip-rect
+API. Every widget is a plain struct you own (usually as a global or
+scene-owned variable). You call its `xxxInit(...)` once, then call its
+`xxxDraw(widget, x, y)` yourself, every frame you want it visible, at whatever
+screen position you choose. Nothing draws itself automatically except three
+fixed system overlays (overscan bars, debug console, FPS counter) — see
+[System overlays](#system-overlays-automatic) below.
+
+### Where UI rendering happens in the frame
+
+- `uiInit()` / `uiDispose()` run once, at engine startup/shutdown.
+- `uiUpdate()` runs once per tick (drives focus-navigation input handling).
+- `uiRender()` runs once per frame, called from inside `sceneRender()` — i.e.
+  **after** the active scene's own 3D/game-world rendering, using an
+  orthographic screen-space projection. Your own widget `xxxDraw()` calls
+  should happen around the same point — typically from your scene's render
+  callback, after world content, so UI draws on top.
+
+## Widgets
+
+Every widget follows the same shape: `xxxInit(widget, ...)` zeroes the struct
+and sets its fields; `xxxDraw(const widget*, x, y) -> errorret_t` draws it at
+that screen position.
+
+> **Init before Draw.** `uislider_t`, `uidropdown_t`, and `uitab_t` cache
+> their label's measured width/height at `Init` time (an optimization —
+> label text doesn't change after that point). Calling `Draw` before `Init`,
+> or mutating `->label` directly instead of re-initializing, leaves stale
+> layout. `uibutton_t`/`uicheckbox_t` don't have this restriction.
+
+### Button
+
+```c
+void       uiButtonInit(uibutton_t *button, const char_t *label);
+bool_t     uiButtonIsHighlighted(const uibutton_t *button);
+void       uiButtonSetHighlighted(uibutton_t *button, bool_t highlighted);
+errorret_t uiButtonDraw(const uibutton_t *button, float_t x, float_t y);
+```
+
+Draws `label` in red when highlighted, white otherwise.
+
+### Checkbox
+
+```c
+void       uiCheckboxInit(uicheckbox_t *checkbox, const char_t *label);
+bool_t     uiCheckboxIsChecked(const uicheckbox_t *checkbox);
+void       uiCheckboxSetChecked(uicheckbox_t *checkbox, bool_t checked);
+void       uiCheckboxToggle(uicheckbox_t *checkbox);
+bool_t     uiCheckboxIsHighlighted(const uicheckbox_t *checkbox);
+void       uiCheckboxSetHighlighted(uicheckbox_t *checkbox, bool_t highlighted);
+errorret_t uiCheckboxDraw(const uicheckbox_t *checkbox, float_t x, float_t y);
+```
+
+Draws `"Y "`/`"N "` then the label.
+
+### Slider
+
+```c
+typedef union { float_t f; int32_t i; } uislidervalue_t;
+
+void     uiSliderInitFloat(uislider_t*, const char_t *label,
+            float_t value, float_t min, float_t max, float_t step);
+void     uiSliderInitInt(uislider_t*, const char_t *label,
+            int32_t value, int32_t min, int32_t max, int32_t step);
+float_t  uiSliderGetFloat(const uislider_t*);   // works for either type
+int32_t  uiSliderGetInt(const uislider_t*);     // asserts type == INT
+void     uiSliderSetFloat(uislider_t*, float_t value);  // asserts type == FLOAT, clamps
+void     uiSliderSetInt(uislider_t*, int32_t value);    // asserts type == INT, clamps
+void     uiSliderStepUp(uislider_t*);     // wraps to min past max
+void     uiSliderStepDown(uislider_t*);   // wraps to max past min
+float_t  uiSliderGetRatio(const uislider_t*);        // normalized 0..1
+int32_t  uiSliderGetStepCount(const uislider_t*);    // 0 for float sliders
+bool_t   uiSliderIsHighlighted(const uislider_t*);
+void     uiSliderSetHighlighted(uislider_t*, bool_t highlighted);
+errorret_t uiSliderDraw(const uislider_t*, float_t x, float_t y);
+```
+
+Draws label, a track, a fill proportional to the current ratio, discrete step
+markers if it's an int slider with fewer than 10 steps, then the value as
+text.
+
+### Dropdown
+
+```c
+void       uiDropdownInit(uidropdown_t *dropdown, const char_t *label,
+              const char_t *const *options, uint8_t optionCount,
+              uint8_t selectedIndex);
+uint8_t    uiDropdownGetSelectedIndex(const uidropdown_t *dropdown);
+const char_t *uiDropdownGetSelectedOption(const uidropdown_t *dropdown);
+void       uiDropdownSetSelectedIndex(uidropdown_t *dropdown, uint8_t index);
+void       uiDropdownStepNext(uidropdown_t *dropdown);   // wraps
+void       uiDropdownStepPrev(uidropdown_t *dropdown);   // wraps
+bool_t     uiDropdownIsHighlighted(const uidropdown_t *dropdown);
+void       uiDropdownSetHighlighted(uidropdown_t *dropdown, bool_t highlighted);
+errorret_t uiDropdownDraw(const uidropdown_t *dropdown, float_t x, float_t y);
+```
+
+`options` is a caller-owned array of strings that must outlive the dropdown
+(it isn't copied). Draws `label` then `"< Option >"`.
+
+### Tab
+
+```c
+void       uiTabInit(uitab_t *tab, const char_t *label);
+bool_t     uiTabIsActive(const uitab_t *tab);
+void       uiTabSetActive(uitab_t *tab, bool_t active);
+errorret_t uiTabDraw(const uitab_t *tab, float_t x, float_t y);
+```
+
+Draws a background box sized to the label (green if active, red if inactive)
+with the label on top.
+
+## Menus: assembling widgets into a navigable list
+
+`uimenu_t` is the one aggregate widget — it owns an array of items (labels,
+spacers, and any of the widgets above), lays them out in a grid, and wires
+keyboard/gamepad navigation via the focus system for you.
+
+```c
+typedef enum {
+  UI_MENU_WIDGET_TYPE_NONE, UI_MENU_WIDGET_TYPE_LABEL,
+  UI_MENU_WIDGET_TYPE_SPACER, UI_MENU_WIDGET_TYPE_CHECKBOX,
+  UI_MENU_WIDGET_TYPE_BUTTON, UI_MENU_WIDGET_TYPE_TAB,
+  UI_MENU_WIDGET_TYPE_SLIDER, UI_MENU_WIDGET_TYPE_DROPDOWN,
+} uimenuwidgettype_t;
+
+void   uiMenuInit(uimenu_t *menu, uimenuselectedcallback_t selected,
+          uimenuclosedcallback_t closed, uimenuchangedcallback_t changed);
+void   uiMenuSetItems(uimenu_t *menu, const uimenuitem_t *items,
+          uint8_t itemCount, uint8_t columns);
+void   uiMenuSetPosition(uimenu_t *menu, uint8_t x, uint8_t y); // focus cursor cell, not pixels
+void   uiMenuOpen(uimenu_t *menu);   // pushes onto the focus stack
+void   uiMenuClose(uimenu_t *menu);  // pops it
+bool_t uiMenuIsActive(const uimenu_t *menu);
+errorret_t uiMenuDraw(const uimenu_t *menu, float_t x, float_t y,
+              float_t width, float_t height);
+```
+
+- `selected(menu, index, item)` fires when the player presses accept on an item.
+- `changed(menu, index, item)` fires when the highlighted item changes.
+- `closed(menu)` fires when the menu is popped off the focus stack.
+- LEFT/RIGHT on a highlighted slider/checkbox/dropdown adjusts its value in
+  place instead of moving focus off it (handled internally).
+
+### Building a menu with the `MENU_*` macros
+
+`uimenu.h` provides macros that cut the boilerplate of filling in a
+`uimenuitem_t` array. They expand into statements using local variables named
+`menu`, `menuIndex`, and `menuCapacity`, so use them together, inside one
+function, starting with `MENU_BEGIN` and ending with `MENU_END`:
+
+```c
+static uimenuitem_t optionsItems[8];
+static uimenu_t optionsMenu;
+static const char_t *qualityOptions[] = { "Low", "Medium", "High" };
+
+static void onOptionsSelected(
+  const uimenu_t *menu, const uint8_t index, const uimenuitem_t *item
+) {
+  if(index == 4) uiMenuClose(&optionsMenu); // "Back" button
+}
+
+static void onOptionsClosed(const uimenu_t *menu) {
+  // e.g. return to the previous screen
+}
+
+void optionsMenuBuild(void) {
+  MENU_BEGIN(&optionsMenu, optionsItems, onOptionsSelected, onOptionsClosed, NULL);
+  MENU_LABEL("Options");
+  MENU_CHECKBOX("Fullscreen");
+  MENU_SLIDER_FLOAT("Volume", 0.8f, 0.0f, 1.0f, 0.05f);
+  MENU_DROPDOWN("Quality", qualityOptions, 3, 1);
+  MENU_BUTTON("Back");
+  MENU_END(optionsItems, 1);
+}
+
+// Once, when the menu screen becomes active:
+uiMenuOpen(&optionsMenu);
+
+// Every frame the menu should be visible:
+uiMenuDraw(&optionsMenu, 20.0f, 20.0f, 200.0f, 100.0f);
+
+// When leaving the menu screen:
+uiMenuClose(&optionsMenu);
+```
+
+`MENU_LABEL`/`MENU_SPACER` force a row break and aren't focusable/selectable.
+Every other `MENU_*` macro calls the matching widget's own `Init` for you.
+
+> This example is constructed directly from the widget/menu API surface (all
+> function and macro signatures above are verified against the source), but
+> there's currently no real menu-building call site anywhere else in the
+> engine to cross-check the *pattern* against — treat it as a starting point,
+> not a copy of shipped code.
+
+## Focus system: navigation underneath `uimenu`
+
+If you're building a custom widget that needs keyboard/gamepad navigation
+without going through `uimenu`, use `ui/focus/uifocus.h` directly. `uimenu`
+is implemented entirely in terms of this API, so it's a reasonable reference.
+
+```c
+uifocusitem_t * uiFocusPush(
+  uint8_t cols, uint8_t rows,
+  uifocusitemcallback_t selected,   // fires on accept
+  uifocusitemcallback_t changed,    // fires on cursor move (and once immediately)
+  uifocusitemcallback_t closed,     // fires on pop
+  uifocusitemdirectioncallback_t direction, // optional pre-empt of a direction press; NULL for default grid movement
+  void *user
+);
+void uiFocusPop(void);
+void uiFocusPopItem(uifocusitem_t *item);
+void uiFocusSetPosition(uifocusitem_t *item, uint8_t x, uint8_t y); // wraps
+void uiFocusMoveDirection(uifocusitem_t *item, uifocusdirection_t dir);
+```
+
+`uiFocusUpdate()` runs automatically from `uiUpdate()` every tick — you don't
+call it yourself. It reads `INPUT_ACTION_ACCEPT` (fires `selected`),
+`INPUT_ACTION_CANCEL` (pops the stack), and the four directional actions
+(with hold-to-repeat timing) to move the cursor within the topmost pushed
+item. Only the topmost stack entry (max depth 8) receives input at a time —
+opening a submenu means pushing a new focus item on top; closing it pops back
+to the parent.
+
+There's no separate "is this widget focused" query — "focused" is expressed
+as the pushed item's current `(x, y)` cursor cell matching a given slot, which
+is exactly how `uimenu`'s `changed` callback decides which item to highlight.
+
+## System overlays (automatic)
+
+Three small overlays are wired into a fixed internal list and draw themselves
+every frame with no call needed from game code:
+
+- **Overscan bars** (`ui/overlay/uicrop.h`) — draws opaque bars over the
+  screen area outside `SCREEN.scanX/scanY/scanWidth/scanHeight` (the
+  overscan-safe viewport). A no-op on platforms/configs where the scan area
+  already equals the full viewport. `UI_CROP.color` (default black) is the
+  only thing you'd normally touch here.
+- **Debug console** (`ui/debug/uiconsole.h`) — draws console history when
+  visible.
+- **FPS counter** (`ui/debug/uifps.h`) — draws a live FPS/frame-time readout.
+
+None of these have a scissor/clip-rect equivalent for your own widgets —
+there is no clipping API in this UI system; everything draws unclipped at
+whatever position you give it.
