- docs/DESIGN.md: the written source of truth for the UI. Decided chapters
(principles, device adaptation, action placement, text stays selectable,
interaction rules, copy, anti-patterns, decision log); controls and
surfaces are marked Pending until the owner picks from the lab.
- /design-lab (dev only): renders each open decision's variants with the
app's real CSS, themes and font scale. Batch A = six control decisions.
- devOnlyGuard: a production build fails if anything under src/design-lab
reaches the bundle (seen red with an unguarded import).
- Size contract: tablet portrait + landscape and up, replacing the
1024x768 floor with its never-built "too small" message.
A focused button that turns natively disabled loses the focus to <body> in
Chrome. The app disables the very button that was pressed on ~60 sites — a
mutation pending, a pager at its last page, undo with nothing left, a player
at the end of its queue, a form gone clean — so a keyboard user was thrown
out of the page on every such press.
One primitive instead of a fix per site: ui/FocusSafeButton renders a
focused-and-disabled (or busy) button as aria-disabled with a click guard,
and applies the native attribute again once the focus is elsewhere. It asks
the document at render time as well as listening for focus events, because
a window without focus fires none (measured). ui/Button and ui/form's Switch
are built on it; 57 hand-rolled buttons swapped their tag for it keeping
their classes, and three hand-copies of the rule (the channel page's Block
and Hide, ChannelDiscovery's Subscribe) now pass `busy`. The soft state's
dim look is one rule in index.css.
`local/focus-safe-disabled` refuses a new raw <button disabled>, pinned by
focusSafe.contract.test.ts. lib/plexDetailUi moved to components/: it is
components, and lib may not import the primitive.
Measured on localdev in Chrome: the audit log's Next button keeps the focus
on reaching the last page, reads aria-disabled, and the guarded click does
nothing.
- Home's rail handed each card a fresh `() => menu.triggerProps(c)` per
render, defeating memo(VideoCard) on every tile whenever the menu's own
state changed. `useItemTriggers` (ui/useContextMenu) keeps one trigger per
item, index-aligned; tested for identity across renders.
- The Button accessible-name union had one hole: `<Button icon={…} />` with
no children and no size typechecked into a nameless button. A textful
button now needs children or a name; pinned with @ts-expect-error.
- comfortPin's header said the pin belongs "on every card and row", which
the code never meant (an episode, a season, a person are not pin kinds).
It now says what is pinnable — and the show page's Related strip, whose
shows ARE pinnable, gets the pin menu it was missing (and a rem width).
- gridColumns / feedView / VirtualGrid claimed layouts 1024–2560 are
"byte-identical" under the column cap; the small cards are capped at 2560
with the filter rail collapsed. The comments say so.
Measured in Chrome before each change:
- A dialog opened from a menu lost its focus: the menu row ran its action
and closed in one batch, and floating-ui's focus return (a microtask)
moved the focus to the row BEHIND the confirm dialog's scrim 7 ms after
it opened, where Enter activated the row. MenuItemList now closes first
and runs the action a task later; the dialog also captures the row, not
a dying menu item, as its restore target.
- A side panel opened as a flyout collapsed the moment a dialog opened
from inside it, unmounting the row the dialog hands the focus back to.
useHoverFocusWithin holds while the focus is inside an aria-modal dialog.
- ui/Button's loading state set native disabled; Chrome moved the focus of
the pressed button to <body> and never gave it back. Loading is now
aria-disabled with a click guard that also cancels implicit submission.
- Escape/Enter in the playlist rail's rename field dropped the focus on
<body>. The row refocuses from its ref callback when it re-attaches (a
post-commit focus sticks; the earlier attempt ran before the button
existed).
- PlayerModal was the one aria-modal shell without the dialog contract:
it is now named by its title, traps Tab, restores the focus to its
opener and shares one counted body scroll lock with every dialog.
Finishes round 1. Part 1 took the runtime bugs; this takes the prose that
had gone false and the three "the comment says so" gaps behind it.
CLAUDE.md is auto-loaded into every agent session and ui/README.md is
not, so an architecture paragraph that still described a flat components
bag was the most expensive stale sentence in the repo: the next agent
adding a popover reads it, sees no platform layer, and writes the generic
component into components/ — the invisible-layer failure this epic exists
to end. It now names components/ui/ and says the boundary is lint-enforced.
The canonical-patterns table gained the three rows the epic established:
ui/Button over a hand-rolled <button>, a keymap row over a private keydown
listener, and disabled-when-busy vs inert-when-inapplicable.
ui/README.md's inventory was written in this branch's first commit and
never learned about CommandPalette, ContextMenu/useContextMenu,
KeyboardHelp or gridColumns — in a section whose own closing rule is that
a second component painting the same thing is how the last inconsistency
happened. It also claimed "everything is rem-derived" while VirtualGrid's
minCol/GRID_GAP are deliberately px; that is now stated as the exception
it is, and a new section records which promises here are tests rather
than sentences.
Three contracts stopped being prose:
- A text-less Button must carry a name. "Required for iconOnly" was a doc
comment, which is why the migration shipped two nameless icon buttons
through eight green lanes. It is a union now, covering both spellings
(iconOnly, and size="icon"/"icon-sm"), satisfied by label, aria-label or
title. It caught one more on the way in: Banner's dismiss took an
optional dismissTitle, so it could render unnamed — it falls back to
common.close now.
- gridColumns' gutter arithmetic. Every existing assertion survived
replacing floor((w + GAP) / (minCol + GAP)) with the naive
floor(w / (minCol + GAP)): the fixed widths agree, the capped cases are
cap-bound, and the loops compare columnsFor against itself. Pinned at
the exact-fit boundaries where the two first disagree (536 and 828).
- ShareDialog's link row. Only Copy was migrated in S1, leaving one 2rem
button between two 1.75rem ones — and on a coarse pointer .touch-target
grew only the migrated one to 2.75rem while the destructive Revoke
stayed small.
Also: the maxCols docstring said 8 columns of 384px where the test it
shipped with asserts 369.
The epic-end review found 32 verified issues. This is the first fix round:
the three highs, the user-facing mediums, and the tests that were passing
for the wrong reason. Docs and the remaining low-severity tail are next.
The boundary rule was the worst of them. Both `no-restricted-imports`
regexes were written in plain "..." literals, where `\.` is an unknown
escape that collapses to the any-char `.` — so the rule read like a
boundary and matched far less than one. `../../lib/api` (the barrel every
feature component imports) and `../../components/Feed` (the same file
`../Feed` names) both sailed through a green gate. String.raw, a third
pattern for the second spelling, and a vitest over ESLint.lintText so a
rule that silently matches nothing can never look like a clean codebase
again.
closeThenNavigate waited for exactly one reclaim popstate. With a second
Back-closable layer still mounted — a palette opened over the player —
the navigation unmounted that layer too, and its reconcile backed over
the entry the navigation had just pushed: "go to Channels" closed the
player and landed on the feed. It now waits for the LAST programmatic
back, then adopts the entries the navigation buried, and falls back after
250ms rather than hanging if no popstate is ever coming.
The rail's inline rename died on arrival. With no domReference, floating-
ui's returnFocus falls through to a module-global stack and restores some
unrelated element from an earlier popover — blurring the field into its
own commit-and-close, from the second popover of a session onward. The
context menu now owns the restore: back to the row, but only if the row
is still there and nothing else has claimed focus.
Also:
- Backspace under the cheat sheet stopped Plex playback and dropped to
the grid; `back` now defers to any layer above, like `escape` beside it.
- A move invalidated only the source list, so the target kept serving
pre-move contents for 30s while the rail already counted N+1.
- Every move error a user can reach is a 404, which `req` leaves to the
caller — so the row snapped back in silence and the shipped moveErrors
strings were unreachable.
- swallowClick armed on long-press but was disarmed only by the click it
was armed for; any press that produced no click ate the next tap on the
whole list.
- The context menu stayed parked over whatever row scrolled under it.
- overflow-clip on the chip lanes ate the focus ring's top and bottom.
- "Why is this off" rode on disabled rows, which show no tooltip and take
no focus: a new `inert` item keeps the reason readable.
- Shift+F10 was advertised app-wide but wired only on Playlists; it has
its own scope now, and useContextMenu matches through the shared parser
instead of its own literals.
- Mod+K could not close the palette, `h` machine-gunned on auto-repeat,
and both were bound above the branch that mounts their overlays.
- Palette options were in the tab order under aria-activedescendant, and
a scroll-synthesised mousemove stole the keyboard selection.
- The OSD live region was created together with its own text.
- Ending a rename stranded focus on <body>.
- The Button variants' hover halves are `enabled:` — the one migrated
site that had guarded its own lost the guard on the way in.
- HU builtinLocked named the list "Watch later" in a Hungarian sentence.
Tests: the chip-lane contract counted per FILE, so a second hand-rolled
lane in an already-compliant file was invisible; the closeThenNavigate
ordering test only passed on a popstate left behind by its neighbours and
failed alone, so it moved to its own file.
S1c, the last part of S1. The contract now lives in components/ui/ and
in one CSS recipe instead of in ~160 call sites:
- Minimum target 2.75rem, on coarse pointers only (.touch-target). A
32px icon button is fine with a mouse -- precise pointer, hover to
confirm the aim -- and not fine with a thumb, so it grows exactly where
there is no precise pointer, which on this app's real second device is
the tablet. It grows the real box rather than painting an invisible
::after hit area, because two expanded hit areas on icon buttons 4px
apart would overlap and the overlap fires the WRONG button. `link` is
excluded: it is text inside a sentence.
- 2.75rem rather than 44px so the target obeys the text-size slider like
everything else; verified that the type/geometry ladder was already
rem-derived off --font-scale, so nothing else was needed there.
- The ladder is documented as a closed set in Button.tsx, with the site
counts it was derived from, and ui/README.md states the contract.
Measured in the browser: fine pointer 36x36 and 34px-tall buttons
(unchanged), coarse pointer the same buttons at 44x44 and 44px tall.
1024x768 renders identically. 3x tsc, eslint, knip, prettier and 690
vitest green.
Second sweep, 34 more sites: NotificationsPanel (14 -- eight identical
accent text links, three ghost icon buttons, two ghost text actions),
Welcome's five auth links, KeyGate, Messages, NavSidebar, ChatThread,
ShareDialog, ChannelPage, PlexPlaylistView, PlexPlaylistAdd,
PlexCollectionEditor and plexViews.
Moves the font-weight out of Button's BASE and into each variant, so the
`link` variant can be semibold (which is what every text link in this app
looks like) while the action variants stay medium, and no element can end
up with two font-* utilities.
Welcome is the one signed-out surface this session cannot see, so only
its byte-identical link swaps were taken; its primary submit and the
bg-card button family are left for a pass that can UAT the screen.
3x tsc, eslint, knip, prettier, 689 vitest green; UAT on Notifications,
Messages and the nav rail, clean console in a fresh tab.
Counting the un-migrated call sites showed the primitive and the app had
drifted into two different looks: the majority of hand-rolled buttons
hover to accent (outline) and fill with card (ghost), while Button
hovered to fg and filled with surface. That split is the inconsistency
this epic exists to remove, so the primitive follows the majority rather
than the other way round -- 16 existing call sites shift slightly, ~90
hand-rolled ones stop being special.
Adds the variants the call sites prove are missing (outline-accent,
outline-danger, outline-warn, link), an icon-sm size for the p-1.5 icon
family, and a size=none so a link owns no button padding; renames
danger-outline to danger-soft so it cannot be confused with
outline-danger (red at rest vs red on hover). Two new tests lock the
link-size default and the rule that a variant never adds a second
font-weight utility -- without tailwind-merge, two font-* utilities are
decided by stylesheet order, not class order, so that is a real hazard.
Migrates AdminUsers, AuditLog, Channels, TagManager, Playlists,
PlaylistsRail and SettingsPanel (Button call sites 37 -> 52). Left alone
deliberately: conditional-paint sites, video-overlay white buttons, drag
handles, chip removers and card-click targets -- the families Button's
own docstring excludes.
3x tsc, eslint, knip, prettier and 689 vitest green; visual UAT on Users,
Access requests and Playlists at 1280x900, no console errors.
- Button: `loading` always disables (|| not ??) — stops a double-submit
when a call-site passes an explicit boolean `disabled` (VideoEditor).
- playlists: track un-ingestable-but-live YouTube ids in the sync baseline
so a linked playlist containing a private/deleted video converges instead
of re-classifying it as a pending pull forever; re-attempt ingestion each
sync so a restored (private->public) video heals, and prune ids that
leave YouTube.
- SettingsPanel: download-auth section renders an honest error/loading
state (StateMessage + retry) instead of a bare empty section on a failed
credentials fetch; HU+EN loadError string.
- tests: reorder-order, partial-failure baseline hold, un-ingestable
converge/heal/prune, Button loading-disables, download-auth error/retry.
Introduce frontend/src/components/ui/Button.tsx — the one action-button primitive
(variants primary|danger|outline|ghost|glass|danger-outline; sizes xs|sm|md|lg|icon;
icon/iconOnly/label/loading/fullWidth/forwardRef). No focus-visible (already centralized
in index.css @layer base). Migrate the cleanest proof sites off btnCls, and flip the
channel Subscribe button to the outline variant so it matches Full history (the user's ask).
