Player chrome — minimal, bottom-anchored
Apple TV owns the player. Minimal overlay: bold filename bottom-left, two glass circles top-right (CC focused white, audio glass), hairline scrubber in the bottom safe area, mono timecodes. No transport buttons — the Siri Remote owns play/pause/scrub. Android TV, Roku, and Smart-TV web mirror this shape, but their apps draw the chrome because those platforms don't ship a system player.
