Audit v2 missing UX: full player had no way to escape except system
back. Two additions:
- Chevron-down close button as the Scaffold topBar navigation icon.
Transparent background so the gradient/cover behind shows through.
- Vertical drag-down on the whole screen pops back past a 200px
threshold, mirroring Flutter's modal-page gesture. Horizontal
scrubs on the slider still work because the gesture detector is
specifically vertical-only.
