// Cinematic export (spec M12, lane E). STUB — lane E fills THIS FILE ONLY.
//
// Pre-wired by foundation2: the hidden ⏺ button (#btn-export in index.html), this module's
// import + init() call in main.js, and the transport hooks
// `transport.captureAudioStream()` -> MediaStream tapping the live WebAudio mix (post-gain,
// spatial included) and `transport.releaseAudioStream()` when done.
//
// When implementing: unhide the button, set `ready = true`; on click seek to the first
// camPath keyframe, play the path, mux scene3d canvas `captureStream(30)` + the audio stream
// with MediaRecorder (video/webm;codecs=vp9,opus), stop at the last keyframe, download
// `festival4d-cut.webm`, then RESTORE all prior UI/transport state. The canvas is
// `scene3d.renderer.domElement`. MediaRecorder needs a *focused* tab to capture real frames
// (pitfall #2) — say so in your evidence if you couldn't.
