Paused playback now shows a bottom panel with channel + title + views + upload date and position instead of the controller bar (which hid itself while paused - it was colliding with custom info). The controller no longer flashes 4 s at playback start: it only reveals on UP/DOWN-style keys. For the TV frame-rate complaint: thumbnails decode at 480x270 RGB_565 via a global Coil loader and avatars at 160px, instead of full-size 1080p+ jpegs re-composited per scroll frame. Measured on the software-rendered emulator: stable 10% janky / p50 18ms during row scrolling; real-hardware measurement via scripts/fps-check.sh when the couch is free. BACK from a Home row also refocuses the watched card now (row-local focus requesters + restore token), fixing the 'focus lands two-three cards left' complaint.
