- PageShell names the page with a visually hidden h1; a view with its own title renders it as
PageHeading and the hidden one steps aside (contract: no hand <h1> inside the shell).
- Section captions are SectionLabel headings (h2, h3 in a dialog), ui/form Section included.
- "Skip to content" is the first Tab stop and focuses the scroller's <main>.
- Below 600px of height the band's filter row folds into "Filters · n" (Feed, Plex, server log),
the same row shown in place.
- The band holds controls only: Downloads and Notifications lose their title cards, the Config and
channel-discovery intros scroll with the content, the Stats tabs and the audit pager join the band,
and the server log's toolbar sticks with the fade under it.
The second half of the button sweep: the remaining hand-rolled buttons in
feature components, the design lab and the components/ui composites now
stand on Button, IconButton, Pressable, Chip or DragHandle.
- Chip + DismissibleChip (filter / token / tag / suggest / ghost, 24px
floor, 44 on touch) replace five chip geometries; FilterChipGroup
renders Chips; overflow lanes measure a mirror painted by chipClass.
- The Plex control row is IconButton's player rung (36, 20px glyph,
round, overlay; 44 on touch); the YT modal bar is on the sm rung with
pressed cycle toggles and names that survive a folded label.
- New variants: IconButton ghost-accent, danger-soft; Button warn on a
new state-warn utility. The .btn-{tone} recipes and btnCls are gone.
- Fixed on the way: membership rows (collection editor, Plex playlist
add) announce checked/mixed; a one-letter tag chip was 21px wide;
descriptionLinks moved out of lib/ (it renders components).
- local/button-primitive: a raw <button>/<FocusSafeButton> outside the
control-primitive files is a lint error (contract-tested, seen red).
Third and last slice of the E11 keyboard layer (S4c). S4a/S4b covered every card grid and rail; the
table-shaped pages — the channel manager, a playlist, the download center — were still Tab-stop
country: a channel row carries a priority stepper, four action buttons and a tag picker before the next
row's name.
- `ui/DataTable keyboardNav`: the rows are the items, Enter clicks the element a column marks
`data-nav-open`. DataTable renders its rows twice (a table, and a card list below `md`); both register
and `lib/listNav` now walks only lists on screen (`checkVisibility`), so `j` past the last row never
carries on into the hidden copy.
- `lib/listNav` leaves a key something before it already handled (`defaultPrevented`): during a keyboard
drag a playlist row's grip moves the row with the arrows, and dnd-kit takes the key on the document
before listNav's window listener. Without the guard ↓ moved the focus off the grip and dropped the drag.
- `ui/NavGrid as="tbody"` for a table whose body is the list (the playlist, under dnd-kit's
SortableContext).
- Wired: Subscriptions and Discovery tables, the card layout (`ChannelLayoutGrid` → VirtualGrid
`keyboardNav`), Hidden/Blocked cards (the ChannelLink name is a channel's open element); a playlist's
rows (the title plays; the grip keeps Space/Enter); the download queue, library and shared lists (the
play button opens, `IconBtn open`; a row without one opens nothing).
- `listNav.wiring.contract.test`: `VirtualGrid` and `DataTable` must say `keyboardNav` like `Carousel`,
`DownloadRow` is a card; the audit log's table is the one exemption (its rows open nothing), and an
exemption that no longer matches a tag fails the test.
Measured in Chrome: Channels table j → row, ring round the whole row; a row walked down keeps 12px above
the viewport edge, walked up clears the sticky header by 35px; Enter opens the channel. Cards 3 columns:
→ 0→1, ↓ 1→4. Hidden and Discovery: j + Enter open the channel. Playlist: j + Enter plays, Escape returns
focus to the row; a keyboard drag (Enter on the grip, ↓) moves the row with focus kept on the grip, and
Escape cancels with the order unchanged. Downloads library: Enter plays a video row, does nothing on a
plain file row.
The Hidden and Blocked tabs were a bare row of name chips ("two withered
chips"). Both now render a responsive grid of real channel cards via a shared
ExcludedChannelList: avatar + name + open-on-YouTube (reusing ChannelLink) and
one labelled reversing action (Unhide / Unblock). One presentation, parameterised
by icon/label/action/copy — the two "excluded channel" tabs now match.
Gate green: tsc/eslint-0/prettier/knip clean. Self-E2E'd: Hidden tab renders both
channels as cards with avatars, YT links, and Unhide buttons.
