// An EffectCraft engine instance in a Web Worker (src/worker.rs, src/frames.rs,
// crates/engine/src/offload.rs and remote.rs). The page sends the compiled module, then:
// - job workers: footage files and jobs (Render Queue, analyses, Roto Brush); the worker replies
//   with JSON messages and rendered files;
// - frame workers: footage files and frame messages (project syncs as diffs, render requests,
//   Roto Brush segmentations); the worker replies with frames (pixels transferred).
