// AI users:
//   - Insert the `InputBackend` producer as a World resource under
//     `INPUT_BACKEND_KEY`, then add the `InputFrameStartScan` system token to
//     the schedule. After `world.update()` runs, read the snapshot through
//     `world.getResource<InputSnapshot>('InputSnapshot')` (or the
//     re-exported `INPUT_SNAPSHOT_RESOURCE_KEY` constant).
//   - In a browser context, attach a PointerLock-aware producer with
//     `attachBrowserInputBackend(canvas)`; the returned callable is
//     both a detach handle and an `InputBackend`.
//   - For headless tests / pre-start fixtures, `createInputSnapshot()`
//     returns an empty snapshot whose accessors all evaluate to false /
//     `{ x: 0, y: 0 }` (charter P3: empty signal is the signal).
//
// Single import path:
//   import {
//     attachBrowserInputBackend,
//     INPUT_BACKEND_KEY,
//     InputFrameStartScan,
//     createInputSnapshot,
//     INPUT_SNAPSHOT_RESOURCE_KEY,
//     type InputSnapshot,
//     type InputBackend,
//   } from '@forgeax/engine-input';
