Transport controls for watching the demo in play mode: a compact bar in the bottom letterbox band with previous (restarts the current part first, player convention) / hold-resume / next / replay buttons, the current part's name and local time, a scrub slider across the full timeline, and a time readout. Buttons carry keyboard shortcuts — Left, Space, Right, R.
Seeking across a part boundary rebuilds the target part from scratch; scrubbing backward within the same part keeps its live state (the sim keeps whatever already happened — jump one part back and forward again for a clean replay).
The scene entrypoint drives the lifecycle: init() at demo start, tick()
per frame, handle(id, value) from its onCallback, teardown() on stop.
