Base rest becomes a real cutscene — video panels with baked-in music

The base-rest activity used to render as placeholder color panels with no audio — the structure was there, but there was nothing to look at. It now plays as a real cutscene: two-panel layout, video panels with PNG fallbacks, auto-advancing on playback end.

The cozy folk soundtrack is baked into the MP4s directly rather than layered as a separate track, so the timing is locked to the picture instead of drifting against it.

The screen's location music pauses when the base-rest cutscene opens and resumes when you dismiss it, so the soundtrack isn't fighting with the ambient track underneath.
