## Rationale ## Rationale
- Preserves the `<video>` UX target while handling browser autoplay constraints explicitly. - Preserves the `<video>` UX target while handling browser autoplay constraints explicitly.
- Avoids total playback failure by retaining a tested canvas fallback path.

## Reversibility ## Reversibility
- Remove the fallback timer and unlock wiring to return to a fixed rendering mode. - Remove the unlock wiring (or return to canvas renderer) to restore prior behavior.
