E32 review round 1 (F3–F6).
- Channels' open-row store and the chat dock use lib/store's createStore instead of a hand-rolled
listener set (the chat dock gets a test of its own).
- The Plex backdrop reads prefers-reduced-motion through useMediaQuery; the query string is one
constant (REDUCED_MOTION) for the hook and the carousel's one-off read.
- A link-restored collection filter showed its raw rating_key in the picker while the titles
loaded: usePlexCollectionTitles now says it is pending, the picker draws a placeholder
(labelsPending, as the channel picker does) and so does the chip row.
- The "deleted tag" rule was written twice with two i18n keys and had drifted: the channel manager
showed NO chip for a pick while the tag list loaded, or ever after a failed load, while the pick
still narrowed the table. One rule now (lib/tagPicks), one key (common.deletedTag); the manager's
row shows every pick, as a placeholder while loading and as its id after a failure.
- "A page with a sticky ColumnHead must declare fadeTop: false" lived in
prose: a registry flag on three pages plus an App special case for the
Channels card layout, and the next table page would have re-acquired the
fade-on-the-header defect with every lane green. ColumnHead now registers
itself with the enclosing PageScroller (ui/stickyTop) while mounted; the
registry flag, the App branch and the prop plumbing are gone. Measured on
localdev: the top mask is 0px under Channels' and Audit's headers, 20px on
Home and the Feed.
- ui/DataTable mounted its table AND its card list at every width, one
hidden by CSS: double DOM and render cost, duplicate ids, two keyboard
copies of every row. It now mounts the one the `md` media query calls for
(lib/useMediaQuery); the keyboard test asserts one layout at each width.
- The Plex module's content width went px → rem with the rest of the page.
