/**
 * Animation worker for receiver transforms.
 *
 * The provider installs this worker on animation-candidate video receivers
 * via `receiver.transform = new RTCRtpScriptTransform(worker, { trackId })`.
 * That installation is itself the marking — the provider only transforms
 * tracks it has already identified — so a track becomes active as soon as its
 * transform arrives here, without waiting on a message. The
 * `{ kind: 'animationTrack', ... }` messages remain for un-marking and for
 * transceiver recycling.
 *
 * Frames belonging to marked tracks are checked against the animation
 * protocol with strict sniffing: matching frames are consumed (they are not
 * real video and must not reach the decoder) and their embedded metadata is
 * emitted to the provider; all other frames pass through untouched so real
 * video tracks keep working.
 *
 * Events are emitted via `postMessage` with our usual event envelope
 * (`type: 'animation' | ...`); the provider receives them through
 * `addEventListener('message')`.
