Three in-app player refinements:
- Prev/next stepping: the modal now takes the feed's loaded order as a queue, with
faint arrow zones flanking the card and Shift+Left/Right shortcuts (plain arrows
seek ±5s). The queue is frozen at open so marking the current video watched can't
drop it and reload a different one; auto-advance-on-end stays off for the feed
(it isn't a playlist) — playlists keep theirs.
- Reachable native YouTube controls: the interaction overlay (wheel volume / click
pause / keyboard focus) now covers only the centre band (top-[12%] bottom-[22%]),
leaving the top-right cluster (volume/CC/settings) and the bottom bar (seek /
More videos / fullscreen) clickable. Verified live: settings menu + fullscreen work.
- Hover-intent description: the title popover now waits ~400ms so a quick pass no
longer flashes it.
