- Channel page: the banner and identity block fold away once the grid scrolls
(ui/scrollFold: folds past 32px only if the page can stay scrolled, unfolds
at the very top) and the name rides in the tab row. One Back button in both
states keeps its focus; folded at a tablet width the actions wrap instead of
pushing the page sideways.
- Plex movie and show pages: the TMDB facts over the key crew are the hero's
second column (plexDetailAside), the keywords sit under the text; the show
page shows them for the first time, with the same three toggles. A
collection's hero is sized to its text.
- YouTube player, 1280px and wider: the title, channel, actions, description
and queue sit in a side panel beside the video, which takes the window's
height (1438x809 at 1920x911, was ~1008 wide). The wheel scrolls that panel
while it can and turns the volume elsewhere.
- DESIGN.md decision log: the keywords' place under the text.
