/**

 * the worker boundary. The two paths share a `MessageChannel`-shaped

 *
 * - `"blit"` — host keeps the visible canvas main-thread with a 2D
 *   context. The renderer creates its own internal `OffscreenCanvas`
 *   for GL rendering and emits each completed frame as an
 *   `ImageBitmap` over the control channel; the host blits the bitmap
 *   into the visible canvas via `drawImage`.
