The app's Toaster lives in the content column, which is a stacking context (its `@container` implies
layout containment), so both full-screen players — portalled to <body> at the same z-index — painted
over every toast. Round 1's "a failed Remove is reported" fix was therefore still silent inside the
player: its toast sat under an 80% black, blurred scrim (elementFromPoint returned the scrim), and a
click on it closed the player.
An overlay now mounts its own `<Toaster overlay />`, and exactly one host shows the toasts: the most
recently mounted overlay, else the app's. Same component, same look — and inside the aria-modal
dialog, where a screen reader can still reach it. A click on a toast inside an overlay stays there.
Both players get one (the Plex player's also works in native fullscreen, where nothing outside the
fullscreen element is drawn). Verified on localdev: the removal failure reads above the scrim,
bottom-left, and clicking it leaves the player open.
Deep-review R5 — five defects in the Remove button f76a2afb put inside the YT player:
- It removed from whichever playlist was selected by the time it was pressed, not the one the player
was launched from; the selection can change under an open player (the command palette opens over
it). The launch list is now part of the player snapshot, and the optimistic row removal only
touches the list actually on screen.
- A 403/404 failed in total silence: the catch claimed the global dialog had reported it, but `req`
deliberately leaves those to the caller. It now notifies, as moveItemTo already did (the silent
catch predates this round; the full-screen consumer did not). New key playlists.removeFailed, HU+EN.
- It computed the next item from the cursor as it was when the button was pressed, but prev/next and
auto-advance keep working under the confirm dialog: the viewer was thrown back onto a video they had
moved past. It reads the live cursor, and if they moved on it just drops the item from the queue.
- The button was disabled for the confirm's lifetime, so the dialog's focus restore hit a disabled
element and a keyboard user who cancelled was left on <body>, outside the aria-modal player. A ref
guards the double press instead.
- Its accessible name was a bare "Remove"; it now names its object, like the row control.
The call-site wiring (step on, drop from the queue, close on the last item, leave everything alone
when the removal did not happen) finally has tests. Verified on localdev in the real YT player: a row
reopened at the 136 s it had just stored; Cancel returned focus to the Remove button; a confirmed
removal stepped 1/3 -> 1/2. 10 mutations, each red on its assertion. Scratch list and positions reset.
Items 2, 4, 5 and 7 of the bug hunt, one round. They are independent, but they are all the same
kind of thing: an action that exists somewhere else in the app and is missing where you actually
want it.
**5 — the channel name in the YT player is a link again.** It was a `<button>`, so middle-click and
Ctrl/Cmd-click did nothing on a thing that looks exactly like a link (the YouTube icon beside it IS
an anchor and opens a tab). It is now a real `<a>` whose href is the same `?chan=<id>` URL
`openChannel` pushes, with a plain left click still taking the in-app path — that path does more
than navigate, since the player must close and reclaim its own Back-to-close history entry first.
The "is this click ours or the browser's" test is now ONE predicate (`isPlainLeftClick`), which
VideoCard's card link also uses, so a second such link cannot forget the middle-click arm.
**2 — "Remove" from inside the player.** The parent owns the removal (the SAME `removeItem` the row
menu and the inline ✕ use: one confirm, one optimistic update, one undo-stack rebase), and the
player owns what happens next, because it is the only side that knows which item is playing — its
launch queue is frozen at mount. It drops the item, plays what followed, and closes when the list
runs out. That forced a real fix in Playlists: the player's mount was derived from `shown` every
render, so anything that dropped the launch row yanked the player off the screen mid-playback. That
was a latent edge (change the view and it happens) and the normal case for this feature. The parent
now snapshots what it launched with, and only onClose takes the player down.
**4 — "Move to <the last list you moved to>".** The submenu is two levels deep and moving a run of
videos into the same list is the shape this gets used in. The remembered id is a per-account pref;
the row is derived from `moveTargets`, which already excludes the list you are looking at, so it
cannot offer a move to where the video already is. Remembered only on a SUCCESSFUL move — a
shortcut to a move that failed is a shortcut to failing again. Absent, not disabled, when there is
nothing to repeat: there is nothing to explain.
**7 — the live-YouTube results can be sorted.** Client-side, over the page already loaded. Not a
new `order=` param, and this is the decision worth recording: the owner's case is "even one page of
results", i.e. reorder what is on screen; a re-query would REPLACE the results, which is not what
"sort these" means; and the zero-quota scrape source has no order parameter at all, so a
server-side control would silently do nothing (or quietly cost 100 quota units) depending on which
source served the page. Only keys a search hit carries are offered — `subscribers`/`priority`
describe a subscription, which a search hit is not, and `shuffle` on a ranked list is noise. Its
own pref, so sorting a search page never re-sorts the library behind it.
Verified in the browser on localdev against the real account: the channel name renders as
`<a href="…&chan=…">` and a ctrl-click / middle-click is left to the browser while a plain click
still opens the channel in-app; removing from the player stepped 1/3 → 1/2 onto the next video and
closed on the last one; the row menu grew "Move to “…”" only after a move and only on a list that
is not the target; and the results sort reordered by views 41.7M → 29.8M → 24.2M → 15.8M. (The
pane's own ctrl-click arrives without the modifier — a harness limit, so the modifier cases were
driven as real MouseEvents.) Scratch playlists and the touched prefs were cleaned up afterwards.
22 vitest, mutation-checked against 14 mutations (no href at all · href without the rest of the
query · every click hijacked in-app · the middle-click arm dropped from the predicate · plain click
no longer in-app · always jumping to the top of the list · the removed item left in the queue · no
clamp when the last item goes · an empty queue not reported as "nothing left" · sort-then-reverse
flipping ties · unknown values first · titles compared numerically · shuffle offered on search
results · direction ignored) — each red on exactly the test that names it. Item 4 has no test of
its own: its rule is enforced by construction, not by a check.
The player checkpointed every 5s and the server stored it, but nothing wrote the new
position back into react-query: the close path only marked qk.feed() stale with
refetchType "none", and nothing refetches the feed until it remounts (staleTime 30s,
refetchOnWindowFocus off). So the resume read the position the cache had been FETCHED
with, and the next checkpoint then persisted that older value over the newer one.
Measured on localdev: played to 830s, closed (server had 830), reopened the same card
without a reload -> the row was back to 751s. 79 seconds of progress destroyed by a
reopen, and the card's progress bar never moved either.
The Plex player already solved this for its detail query, with a comment describing the
identical failure; this is the feed-side twin that was missed in that sweep. patchCachedProgress
writes the position the SERVER stored (the endpoint clears trivially-early and near-finished
checkpoints to 0, so mirroring our own reading would disagree with the row) into every cached
feed page and playlist detail, keeping array identity where nothing changed. A session map
covers the second half: the launch queue is frozen at mount, so stepping next->prev back to an
item played earlier in the same session resumed from that snapshot.
Verified in the browser: 811 -> close 816 -> reopen 825, and the card now shows Continue/Restart.
Reaching a channel three modules away cost a rail, a page and a scroll.
Now it costs a keystroke and half a word: Mod+K searches modules,
channels, playlists, the saved views applicable where you stand, and the
app-wide actions.
Scope agreed with the product owner: navigation + actions, but only the
reversible local ones (the shortcuts sheet, the theme). "Sync from
YouTube" is deliberately absent — it is a long-running job against a
quota, it wants the progress and error surface the Channels page already
gives it, and one mistyped Enter is a worse failure than the walk it
would have saved.
Matching is word-wise and accent-folded, because this is a bilingual app
and nobody reaches for the accent keys in a hurry: "pod thevr" finds
TheVR Podcast and "penzugy" finds pénzügy. The arrows walk one flat
result list so crossing a group heading is invisible, and the field
carries the combobox/listbox aria tree that virtual selection needs.
ui/CommandPalette is domain-free (items are a prop, per the ui/ import
rule); AppCommandPalette supplies them. The shell is Modal again, with a
new `top` placement so a search-first dialog grows downwards instead of
jumping as results change.
Also fixes a bug the palette hit on its first run, and that PlayerModal
had already hit once: closing a dialog reclaims its Back-to-close
history entry with a programmatic history.back(), which undoes any
pushState made before it lands — so a command that navigates only closed
the palette. The rule is now closeThenNavigate() in history.ts with a
test, and PlayerModal's inline copy is gone.
The global `h` moves out of KeyboardHelp into useGlobalKeymap beside
Mod+K, so one listener owns the whole `global` scope and dispatch's
exhaustiveness keeps meaning what it says.
The Plex player had a shortcuts overlay nobody else did, so the YouTube
player's Space/F/arrows and the Plex browser's Backspace were documented
nowhere. ui/KeyboardHelp is that sheet for every surface, opened by a
global `h` - not the conventional `?`, which is a Shift chord on a
Hungarian layout, while `h` is the key this app's reader already has in
their fingers from the player.
It renders the shared table filtered to the scopes that are LIVE: a
surface registers its scope with useKeyScope while mounted, and only
while its keys really do something - PlexBrowse deactivates its own
scope inside the player, where its Backspace no-ops, so the sheet cannot
promise a "Back one level" the handler declines to perform. Same rule
for the `when` rows: ⇧←/⇧→ are listed only inside a series, an answer
the player publishes because the sheet cannot ask.
No new overlay primitive, after checking: Modal already portals into
document.fullscreenElement ?? document.body (so this works over a
fullscreen player), registers an Escape layer, traps focus and handles
browser Back. Third time this epic that the thing was already built.
Shift+F10 is in the table as `handledLocally` - documented and sharing
the chord parser, but matched by useContextMenu on the focused row.
dispatch neither routes it nor demands a handler for it, so the
exhaustiveness check stays honest about what it actually covers.
Also: A/S have cycled the Plex audio and subtitle tracks since E5, but
silently - the only way to see where you landed was to open the tracks
menu, the exact round-trip the shortcut exists to avoid. cycleAudio and
cycleSubtitle now return the track they moved to, and the player flashes
it over the video.
Six surfaces each owned a private keydown listener with its own key
literals and its own idea of "am I typing?", and they had drifted:
PlexPlayer matched `case "a"` without checking modifiers, so Ctrl+A
(select all) cycled the audio track, and its typing guard missed
<select> and contentEditable where the other two surfaces covered both.
lib/keymap.ts is a TABLE, not a dispatcher. Each surface keeps its own
listener and closures - PlexPlayer's refs are not worth re-plumbing -
but the chords, the modifier rules and the typing guard live in one
place, and dispatch() binds a scope's rows to handlers through a mapped
type, so a row without a handler (or a handler without a row) is a tsc
error rather than a comment someone forgets.
Matching is now exact on modifiers, which is what kills the Ctrl+A bug
and lets Shift+arrow be its own row beside the bare arrow. Escape opts
out of the typing guard (allowInInput) so it stays the way out of a
player's own subtitle-offset field.
The player's shortcut sheet renders helpLines() instead of a hand-copied
array beside the handler - the two used to be edited separately, which
is how a sheet ends up documenting a key that no longer exists. Labels
move to the new `keys` i18n namespace (EN + HU), and a test asserts
every row is named in both.
The app HAS a platform layer -- AnchoredPopover (22 importers, with
arrows/typeahead/Escape/anchor-flip), QueryState (21), Modal (17),
PageShell, DataTable, Tabs, Tooltip and ~26 more -- but it sat flat among
~160 feature components with nothing marking it as one. Several of those
files describe themselves as 'the one place' or 'canonical' and were
still bypassed by hand-rolled markup, because a layer nobody can see is a
layer nobody uses; three separate inventory passes of this codebase
misread it the same way.
Moves the 33 domain-free modules into components/ui/, rewrites the
imports in 89 files, and makes the boundary a lint rule rather than a
convention: inside ui/ a one-level-up import (a feature component) and
any lib/api slice are errors. The rule was verified to fire on both and
to leave generic lib/ helpers alone. README.md states which side of the
line a component belongs on and why.
No behaviour change: 3x tsc, eslint, knip, prettier and 687 vitest tests
all green; no backend file touched.
UX-8: one Escape must close only the topmost layer, never both an open
popover AND the player beneath it. The popover's Escape listener is on
`document` and fires before the player's on `window`; closing the popover
flushes its layer off the shared stack synchronously, so the player's
`anyLayerAbove()` lookup read "nothing above" and closed too. Add a
consumed-event flag to layerStack (`markEscapeHandled`/`escapeHandled`):
the acting topmost layer stamps the shared KeyboardEvent, and both players
check the stamp before the (now-mutated) stack. Immune to listener order
and mid-dispatch stack mutation. Cover with layerStack.dom.test.ts.
UX-7: the E4 `.reveal` sweep already covered the card action rows; two
residual hover-only traps remained — invisible-but-tappable/Tab-focusable
on touch. Add a group-agnostic `.reveal-hover` recipe (display:none under
`(hover: none)`) paired with each site's own hover/focus-within reveal:
- VideoCard play/Continue/Restart overlay: also reveal on
group-focus-within (keyboard), and drop it on touch — the card tap
already plays/resumes, so no permanent scrim over every mobile thumbnail.
- Carousel prev/next arrows: gone on touch, where the strip swipes.
Mirror the Plex player split (plexPlayerHooks.ts / plexPlayerControls.tsx). The shell
keeps owning the shared refs and passes them into each hook; the once-bound keyboard
handler + layer-stack registration stay in the shell (they orchestrate every cluster).
Behaviour-preserving code-motion — PlayerModal 1332 -> 890 lines.
New lib/playerModalHooks.ts:
- useYtVolume (per-account wheel/arrow volume, on shared playerVolume.ts)
- useNativeControlsYield (iframe-focus overlay yield)
- useYtBigView (F-maximise + our true-fullscreen; YT-specific, not Plex's useFullscreen)
- useYtProgress (player create + resume + 5s checkpoint + auto-watch + auto-advance)
New components/playerModalControls.tsx: PlayerTransportControls (moved as-is) + the
AutoMode/LoopMode types.
Self-E2E (localdev): play a feed video -> plays; transport bar (Auto/Loop); wheel volume
persists ({"volume":100}); F maximises + docked bar; exit big view; Close destroys the
player. Gate green: typecheck, knip, eslint (0 err), prettier, 247 vitest.
Noted a pre-existing bug (kept byte-identical here, flagged separately): the native-yield
effect removes a "blur-sm" listener but adds "blur" — the blur listener leaks.
Fold the hand-rolled server-pref plumbing (savePrefs + local mirror + me-cache
merge + adopt-on-login) into a single usePref<T>(serverKey, default, opts) hook,
plus useSavePref for dynamic multi-key patches.
Migrated (6 savePrefs call sites + 2 duplicated adopt effects -> the hook):
- FeedViewProvider: view
- App: filterCollapsed, playlistsCollapsed (+ their adopt block removed)
- PlayerModal: playerAutoAdvance, playerLoop
- plexDetailUi: plexInfoArtBg/Cast/Related (savePref via useSavePref)
Left as-is by design: panel layouts (a dynamically-indexed Record, not one key),
language (i18n store, no React state), PrefsProvider (debounced multi-field
auto-save + baseline echo-suppression - a different model).
Behaviour-equivalent (net -84 LOC at the call sites). usePref.dom.test covers
the three seed sources, persist path, debounce, adopt, parse, and useSavePref.
Frontend gate green: typecheck, knip, eslint (0 err), prettier, 238 vitest.
Marking a card watched/hidden/reset and closing the player each fired a full
`invalidateQueries(qk.feed())`, refetching EVERY loaded infinite-query page — 10
pages x a few quick marks = ~50 feed refetches, each a full scan (x PERF-1). The
optimistic `overrides` layer + the matchesView filter already render the correct
state (a hidden/watched card drops out instantly), so the refetch was pure waste.
Switch these paths to `refetchType: "none"`: the queries are marked stale but not
refetched now; the next filter change / remount pulls fresh server data. Applies
to the two Feed card-action paths (setState/clearState) and the PlayerModal
close (feed + playlists — progress is already persisted server-side, only the
on-screen resume bar waits for the next natural refetch).
Left as immediate refetch on purpose: channel/tag/playlist mutations (one-off, on
pages where the main feed is unmounted anyway) and the onboarding / notification-
undo paths (which must reveal the changed content right away). Gate green:
frontend tsc/eslint/knip/prettier/222 vitest (backend unchanged, 344 pytest).
Add a paint-only .btn-primary recipe (solid accent bg + accent-fg text +
hover:opacity dim) in index.css @layer components, alongside the selection-paint
recipes (.pill/.chip/.is-current). Migrate ~38 primary/action buttons across 24
files off the hand-rolled 'bg-accent text-accent-fg hover:opacity-90', keeping
each site's geometry (padding/radius/font/gap/disabled/shadow).
Deliberately NOT migrated: accent BADGES/labels (spans), the chat message bubble,
selection toggles (tableHeader — R8 popover territory), and the round play FAB
(hover:scale, not the opacity-dim primary idiom). Three previously hover-less
primary buttons (SettingsPanel/SetupWizard/DraftSaveBar) gain the standard hover
dim for consistency.
Gate green (tsc/eslint-0/prettier/knip/vitest 79); self-E2E confirmed a migrated
button computes to accent/accent-fg and both recipe rules load.
- NotificationsPanel per-row .glass -> glass-card (the rows are cards, not panel surface).
- New .overlay-backdrop recipe (4px blur = backdrop-blur-xs) with a data-perf override that
DROPS the blur. The viewport-sized modal scrim blur (Modal/PlayerModal/Welcome) was a raw
backdrop-blur-xs utility that survived perf mode while every .glass had its blur dropped —
the most expensive blur in the app. Overlays keep their bg-black/NN.
- gotcha: write ONLY the standard backdrop-filter; a manual -webkit- line makes lightningcss
drop the standard prop (webkit-only output -> no blur in Firefox).
The ~124 px-frozen text-[Npx] labels didn't track the Settings font-scale slider
while their rem-sized neighbours did. Add text-2xs (0.6875rem) / text-3xs
(0.625rem) font-size-ONLY tokens (no paired line-height -> matches the arbitrary
they replace, zero vertical-rhythm shift) and codemod every text-[Npx] to a rem
class (rare 8/9/12/13px -> rem arbitraries).
Also: --hdr-h 68px -> 4.25rem so header content clears the rem-sized pills at
scale 1.3 instead of sliding under; NavSidebar/SidePanel slot widths + their
icon/badge px sizes go rem so the rails keep pace with their (now-scaling)
labels; a w-24/h-[54px] thumb -> h-13.5 to preserve 16:9 at scale. Media
thumbnails, page-width caps and fixed container widths deliberately stay px.
Verified via getComputedStyle at scale 1.06/1.3: text-2xs 11.66->14.3px, header
clearance 72->88px, nav slot 246->302px — all scale proportionally.
Add theme-scoped --danger/--warn/--success (+ -fg) tokens wired into the v4
@theme inline, replacing ~110 raw red/amber/emerald/green palette refs across
34 files. Fixes light-theme contrast failures (fixed Tailwind shades fell to
~1.7-3:1 on white). Status colors are scheme-independent — recognised by hue,
shifting only by theme to hold contrast (bright on dark bg, darkened on light).
Solid fills use the paired -fg text; @source inline guarantees the full -fg set
exists. IMDb rating gold kept as a deliberate decorative non-status exception.
- #1: remove the 9 dead `shadow-*` from glass surfaces instead of letting them override the tuned glass
box-shadow. The @layer components move made a JSX shadow-* win AND atomically drop the glass inset
top-edge highlight; deleting the (always-dead) utilities keeps the intended glass depth incl. the
inset sheen. Verified in-browser: a .glass box-shadow again includes its inset segment.
- #3: drop the per-element focus-visible outlines from the rail chrome buttons and SavedViews action
buttons — the global button:focus-visible fallback already draws the identical 2px accent ring, so
they were redundant. Verified: the pin button rings from the global rule alone.
- #5: unify the focus-within outline offset (offset-2) on the SearchBar and ShareDialog pills.
- #2 (double outline on the pill when an inner button is focused): NOT fixed — the clean fix
(has-[input:focus] so only the input rings the pill) does not generate under Tailwind v4 (measured:
no rule emitted). Kept the working focus-within, which is a11y-correct (every element still shows a
focus indicator); the overlapping ring is an accepted cosmetic edge-case.
- #4 (weak ring on solid-fill selected items): deferred to R10 with the selected-paint tokenisation.
Gate green (tsc/eslint/prettier/knip/vitest 79).
Root-fixes the opacity-modifier seed bug behind R10 S0: the theme colors were
bare `var(--x)` hex with no <alpha-value>, so `bg-accent/40`, `ring-accent/40`,
`border-border/60`, `text-muted/70`, … (~99 sites across 45 files) emitted no
CSS rule at all — latent no-ops. v4 implements the opacity modifier via
`color-mix`, so the modifier now works with the existing hex vars, no per-scheme
token duplication needed.
- `npx @tailwindcss/upgrade`: `@tailwind` directives → `@import "tailwindcss"`,
JS config → CSS `@theme` (colors, --font-sans, the z-index tokens preserved),
classname renames (rounded/shadow/blur scale, outline-none→outline-hidden,
ring→ring-2) across 56 files; PostCSS plugin → @tailwindcss/postcss,
autoprefixer removed (v4 prefixes for you).
- `@theme` → `@theme inline` (load-bearing): the color vars are redefined at
runtime under html[data-scheme]/[data-theme]; inline resolves them at the use
site so per-scheme opacity tints track the active scheme (the shadcn v4 pattern).
- Revert one codemod false-positive: it rewrote the English word "rounded" →
"rounded-sm" inside a releaseNotes.ts prose sentence.
Gate green: tsc(app+node) / eslint 0-err / prettier / vitest 79 / knip.
Verified in-browser: bg-accent/15 now computes a scheme-tracking color at 0.15
alpha across all 6 schemes × 2 themes; the hand-rolled glass border/shadow/
radius/backdrop-filter render unchanged under v4.
The large-logical-iframe + CSS-scale-down trick to force a 1080p start did not
work behind the user's work VPN (YouTube caps quality by network there regardless
of viewport size), and the two-phase native switch could downgrade a latched
1080p to 480p on some streams. Not worth the complexity for an unreliable win —
revert to the original "opens at whatever resolution YouTube picks" behaviour;
the user sets 1080p manually via fullscreen + the gear as before.
Kept: the windowed maximise (fullscreen) button added to the player meta row.
Two-phase HD: phase 1 keeps the fixed 1920x1080 iframe scaled down to latch
1080p; once the quality poll sees hd1080, switch to native responsive sizing so
YouTube renders its own controls (the gear especially) at full size instead of
scaled-down. A latched pick survives the shrink on a normal VOD.
CONDITIONAL / under observation: on one was_live stream in dev, quality dropped
hd1080 -> 480p ~2s after going native (YouTube re-caps to the small viewport);
held 1080p elsewhere. Gated behind HD_DROP_TO_NATIVE so phase 2 can be turned
off in one line to fall back to the guaranteed-1080p permanent-scale phase 1.
YouTube picks an embed's quality at player-creation from the iframe's internal
viewport and latches it; a windowed-size embed was stuck ~360-480p, forcing a
manual fullscreen + gear trip to 1080p. Create the iframe at a fixed 1920x1080
logical size and CSS transform-scale it DOWN to fit (a CSS transform doesn't
shrink the internal viewport, so YouTube still serves 1080p, latched for the
session even while it paints small). A letterbox-contain fit via a
ResizeObserver handles both the windowed and big-view boxes. Gated behind
FORCE_HD_LOGICAL_SIZE for an easy revert if a restrictive network overrides it.
Also add a maximise (fullscreen) button to the windowed player's meta row: the
only fullscreen control reachable in the windowed video was YouTube's own, which
hides our chrome. It mirrors the F key and leads to the docked bar + our true
fullscreen. Corrects the stale code note that claimed the scale trick fails
(that was scaling a SMALL player up; scaling a LARGE player down works).
Two R8 S5 (player big-view control-bar) follow-ups:
- Modal now portals into `document.fullscreenElement ?? document.body` (reactive), the
same fullscreen-aware root the popover platform uses. A node under <body> is painted
beneath whatever holds the fullscreen lock, so the download dialog — a Modal, opened
from the player's control bar — would open invisibly in true fullscreen. With that
fixed, the `!isFullscreen` guard on the player's DownloadButton is dropped, so download
joins add-to-playlist as working in true fullscreen. (Every Modal is now fullscreen-
aware; the fix is at the primitive, not the call site.)
- The queue transport cluster (prev / counter / next + auto-advance + loop toggles) was
duplicated inline in two places — the modal queue bar and the big-view docked control
bar — with identical logic and only theme + label-visibility differing. Extracted a
`<PlayerTransportControls variant="modal"|"docked">`; a mode/icon change now lands once.
Behaviour-preserving (the docked bar's trailing divider and the wrapper rows stay at the
call sites). Note the modal variant keeps its `bg-accent/15` active tint, which is a
latent no-op under Tailwind v3's hex --accent — left as-is for R10 S0's styling audit.
Gate green (tsc/eslint/76 vitest). Device-UAT'd in real Chrome: transport controls render
correctly in both the modal queue bar and the docked bar; the download button now shows in
true fullscreen and its dialog portals into the fullscreen stage, fully visible and
centered. No console errors.
Correctness:
- Escape is now strictly topmost-only for EVERY mode. Hover popovers register in
the shared layerStack too (and floating-ui's own Escape is off for all modes), so
an open tooltip/hover-card no longer either swallows the Escape from a Modal/player
underneath (its document-level stopPropagation vs their window listeners) or
double-closes both. A player's own overlay hover-card now takes Escape before the
player, keeping it alive.
- An invisible (referenceHidden, scrolled-out) surface is no longer a dismissable
layer, so it can't silently eat an Escape aimed at what's actually on screen, nor
make a player defer.
- PopoverSurface splits into a wrapper that returns null before any hook and an inner
that holds them, so a mounted-but-closed popover (≈10 per table row) subscribes no
fullscreen listeners — was ~1800 document listeners on a 100-row table.
- The fullscreen portal no longer remounts on a key: one persistent container is
re-parented body↔fullscreen-element with appendChild (atomic move), so the open
panel's focus/caret/scroll/animation survive a transition and an element SWAP is
handled by the element-identity dependency.
- AddToPlaylist drops `disabled={busy}` on its items (it blurred the focused item to
<body> and permanently killed roving focus); re-entrancy is already guarded in
toggle(), and aria-busy conveys the pending state.
- New `hostsInput` option turns off BOTH typeahead and focus-item-on-hover for the two
menus with an inline text field, so a pointer passing over a list item no longer
steals the field's caret and mis-routes the next Enter. Replaces their `typeahead:false`.
- ChannelTags' single-pass fit loop gains a whole-set fast path, so it stops collapsing
chips into "+N" when they would all have fitted.
- `initialFocus={-1}` is applied only when a `selectedIndex` is set (the sync-focus race
it works around); a plain nav menu now lets the focus manager focus normally, so an
item-less menu (first-run tag editor) still has a keyboard entry point.
a11y:
- `ariaLabel` now wins on menu-role panels — the surface strips useRole's competing
`aria-labelledby` when an explicit label is given (verified: the filter/View menus
are named by their column/label, not the trigger).
- PopoverItem routes caller props THROUGH getItemProps and applies its own
tabIndex/disabled/data-active/className last, so a caller handler or tabIndex can no
longer be silently dropped or clobber the roving model.
Regressions / consistency:
- Tooltip shows/hides on contact again (explicit 0/0 hover delay) instead of inheriting
the platform's 120/140 ms intent delay.
- ChannelTags' editor list regains its useScrollFade overflow mask.
- ChannelTagsControl takes a `bounded` prop; the channel detail page passes false so
tags show inline in the wide header instead of collapsing to "+N".
- ChannelPage's tag-catalog query is gated on subscribed && !demo (matches the only
consumer's render condition); the manager's tag toggle now also invalidates
qk.channel(id) so the detail page's cached tags stay in step.
- DetailCustomizeMenu + PrefToggle revert off the platform to the pre-R8 inline
`absolute` menu: in the player's overlay it renders inside a transform:scale(1.25)
subtree, and portalling out to <body> painted it at 1×. Same reason the player's own
menus stay hand-rolled; this also restores PrefToggle to plain buttons (the rows are
independent toggles, not a radio group). The stale PlayerModal fullscreen comment is
corrected too.
Gate green (tsc/eslint/76 vitest). Self-UAT in-browser: hover-over-item no longer
steals the tag input's caret; text filter keeps caret while narrowing; menu aria-label
is the label not the trigger; selectedIndex lands focus on the checked item; roving +
Escape-close+refocus intact; add-to-playlist items never disabled. NOT verified here
(needs a device / playing media): the fullscreen portal reparent and the player-overlay
paths — owed device UAT, as they already were.
The description hover card loses its two hand-managed timers and its fixed `bottom`
anchor. It now opens above the title through the platform, which means `flip` can rescue
it when there is no room up there either — the old fixed anchor could only grow upward.
Its width moves from a px clamp to a rem one, so it follows the font-scale slider like
the rest of the app.
Add-to-playlist is no longer disabled in the player's true fullscreen: its menu rides
the platform, which portals into the fullscreen element rather than <body>. The download
button stays hidden there on purpose — it opens a Modal, and Modal still portals to
<body>, so its dialog would open invisibly. Lifting that needs the same fullscreen-aware
root inside Modal.
NOT migrated, deliberately: PlexPlayer's gear and tracks panels. They are the one place
where portalling would be a visual regression — the control bar sits inside the player's
`transform: scale(1.25)` windowed subtree, so a panel portaled out of it renders at 80%
of the surrounding UI's size. Positioning would still be correct (floating-ui reads
post-transform viewport rects); the panel's own type and padding would not. Doing this
properly means either portalling into that scaled wrapper or dropping the scale, and
either way it needs a UAT with a playing video that this environment cannot run.
Verified in-browser: the description card opens after its hover-intent delay, anchored
8px above the title and left-aligned to it, with the description loaded.
Replace the three mutually-unaware Escape systems — Modal's private modalStack,
the popovers' document listeners with a blanket stopPropagation, and the two
players' modalCount() checks — with one shared lib/layerStack.ts. Every open
dismissable layer registers in open order; a layer acts on Escape only when it
is topmost, and reads anyLayerAbove() to decide whether to defer. Coordination
is now a stack lookup, not event-propagation order, so it no longer depends on
which listener happens to fire first.
- Modal + useDismiss register via the stack; useDismiss drops the blanket
stopPropagation (its documented side effect: it swallowed a player's own
Escape while any popover was open).
- Both players register as a layer and defer via anyLayerAbove() instead of
modalCount(); PlayerModal checks it before its maximise/fullscreen steps.
A player MENU is a layer too, so it closes first and the next Escape reaches
the auto-skip-cancel — fixing the documented PlexPlayer bug.
- AnchoredPopover routes non-hover Escape through the stack (floating-ui's own
escapeKey off there) and registers as a layer, so a player/modal underneath
defers once S4 migrates the in-player menus. FloatingTree still owns
popover-vs-popover ordering; the stack adds the cross-type ordering.
Removes all 13 remaining `any`s and flips the ESLint rule from off to error so
new ones can't creep back:
- api.ts prefs/data JSON bags: Record<string, any> -> Record<string, unknown>,
narrowed at consumers (App language guard; NotificationsPanel shapes the
notification `data` per type behind its existing typeof guards)
- catch (e: any) -> catch (e) + `e instanceof HttpError` narrowing
(SettingsPanel, SetupWizard, PlexPlayer)
- the YouTube IFrame API boundary: new lib/youtube.ts types (YTPlayer/
YTPlayerEvent/YTNamespace + a Window augmentation) replace the 6 player anys;
tsc surfaced the exact method surface to declare
- NotificationsPanel `t` props: any-options -> i18next TFunction
Gate green: typecheck (app+node+e2e), eslint 0 errors (rule now enforced),
prettier, 74 vitest.
Video.status, Playlist.kind/source (+ PlaylistDetail), DownloadJob.job_kind
were bare `string`; type them as named unions verified against the backend
(VALID_STATES={new,watched,hidden}; kind user|watch_later; source local|
youtube; job_kind download|edit). VideoStatus then propagates through the
optimistic-override map, onState, and the VideoCard/VirtualFeed/PlayerModal
props — tsc now rejects a status typo (e.g. a stale "in_progress", which is a
derived filter, never a stored status) at every call site.
Extend lib/queryKeys.ts to the remaining ~34 key roots and migrate every
remaining literal (queryKey: [...] AND the positional useLiveQuery keys) in
36 files. All ~200 React Query keys across the app now route through the
factory; zero raw key literals remain outside queryKeys.ts.
The heterogeneous composite plex keys (plex-library/facets/collections/
playlists carry a filters object, a ratingKeys array, or a union/group
discriminator) take a variadic pass-through — the factory centralizes the
ROOT string; single-id keys stay precisely typed. Nullable keys (thread,
playlist, ytSearch) accept null so a null segment is preserved.
Pure substitution — byte-identical key arrays, so TanStack prefix matching
is unchanged. Gate green: typecheck (app+node+e2e), eslint (0 err),
prettier, 68 vitest. Runtime-verified on a fresh dev server: Feed + Plex
modules load, feed/facets/tags/my-status/plex-library/plex-facets/
plex-collections/plex-playlists all 200, full UI renders.
Introduce lib/queryKeys.ts as the single source of truth for React Query
keys — the R7 driver was ~200 hand-written key literals across 51 files
(`["feed"]` alone in 15+), where one typo silently orphans a key so an
invalidate never matches.
S2a migrates the three highest-traffic domains (feed/video, channels,
playlists) plus the shared me/my-status/tags roots: ~90 literal sites in
18 files now call qk.*(). Pure substitution — each factory fn returns the
byte-identical array the call sites used before, so TanStack's prefix
matching is unchanged (qk.feed() still invalidates qk.feed(filters)).
Co-invalidation clusters are deliberately NOT bundled into helpers (they
differ per site), so no query's refetch scope changes.
Nullable keys (playlist(selectedId), ytSearch(q)) accept null so a null
segment is preserved (["playlist", null]) while a no-arg call is the bare
prefix key — guard is `!== undefined`.
Gate green: typecheck, eslint (0 err), prettier, 68 vitest. Smoke: app
boots, feed/facets/tags/my-status all 200, no console errors. Factory
extended to plex/messaging/admin/downloads/notifications in S2b.
justify-center + overflow-x-auto stranded the left-end controls (Previous, the
N/M counter) when the bar overflowed a narrow window. justify-start makes the
overflow scroll from the start — and matches the conventional left-aligned
video-player control bar.
The overlaid, auto-hiding bar fought YouTube's seek bar for the same bottom
pixels: while ours showed it covered YT's seek + buttons, and reaching them
meant moving off the area and waiting for our bar to fade — a fiddly, "random"-
feeling dance keyed on mouse movement.
Now the bar is DOCKED and always visible: the video area is inset by the bar's
height (a wrapper around the mount, since YT.Player replaces the mount element
with its iframe and would drop a class set on it), so the bar sits in its own
strip and never overlaps the video. YouTube's seek/controls stay reachable by
hovering the video's bottom edge, just above ours. No auto-hide, no guessing,
no fight. Verified in Chrome: iframe.bottom == bar.top (no overlap), bar opacity 1.
UAT feedback on the F-maximise view — three fixes:
- Own control bar in the big views (maximise + our fullscreen): previous/next +
N/M, auto-advance, loop, add-to-playlist, download, mark-watched, exit, and a
true-fullscreen toggle. Auto-hides on idle. Add/download are hidden in true
fullscreen (their popovers portal to <body>, outside the fullscreen element).
- Wheel volume works in the big views again: the centre interaction overlay is
now armed in maximise/fullscreen (it only yields to YouTube's own settings
menu), so the wheel bubbles to our handler instead of the bare iframe. F also
offers true fullscreen that WE own (Fullscreen API on the stage), so wheel/
arrow volume and our controls work inside it too — YouTube's own fullscreen
button, which we never surface, is not involved.
- Back (mouse/browser) steps out one level at a time via nested history layers
(useBackToExit): fullscreen -> maximise -> the modal -> closed, instead of
closing the whole player at once.
Verified in Chrome: wheel volume in maximise + fullscreen, the control bar, and
the full Back ladder (fullscreen -> maximise -> modal -> closed).
The worst one was, again, the previous round's own fix.
- Round 7 stopped awaiting the HLS sweep so startup could serve immediately — which
also made it run CONCURRENTLY with playback, and `sweep_orphans` snapshotted the
live-session set BEFORE listing the root and rmtree'd outside the lock. Since
`start_session` reuses a directory path for the same (key, offset, tag), a stale
name can become a live session at any moment. Two guards now: nothing whose mtime
is newer than this process's start is ever deleted, and the live check + rmtree
happen together under the lock, one directory at a time.
- The sweep task is awaited after cancel, so shutdown can't leave it pending.
- `_rate_limiter` used a truthiness test on its timestamp, so a `now()` of exactly
0.0 read as "never ran" — unreachable in production, but `now` exists to be
injected and a test clock starting at 0 is the obvious choice.
- The RSS total-outage error now carries the first underlying error: "all N channels
failed" is also what ONE dead feed id looks like on a small instance, and a red
card the user can't act on is its own kind of dishonest.
- The WebKit fullscreen handling moved into `lib/fullscreen` and PlexPlayer uses it
too — it had the same unprefixed-only reads in three places, including an Escape
branch that would have closed the whole player instead of leaving fullscreen.
- The `--max` CSS comment claimed `inset: 0` did the sizing; Tailwind's `w-full` is
still on the element and wins. Comment now states the real mechanism.
Verified in real Chrome (the pane can't composite or do native fullscreen):
- F fills the 1920x889 viewport; the exit pill renders top-right on the letterbox
band and overlaps NO YouTube control — the collision this round suspected does not
reproduce in this embed (its own buttons sit bottom-left / bottom-right).
- Four real ArrowDown presses while maximised: persisted volume 100 -> 80, with the
level flash visible on screen.
- A real click on the exit pill un-maximises and returns focus to the card.
- lib/fullscreen driven from a real click: enter (innerHeight 889 -> 1024), the
change listener fires exactly once per transition, exit returns to 889.
Backend suite 150 -> 158; the new sweep tests are mutation-checked, and they read
their cutoff from the filesystem rather than a clock (the container VM and the
bind-mounted host disagree by enough to make a clock-based assertion flaky).
Five of them sit where round 6 turned F from a Fullscreen API call into a CSS
maximise: the guards around it still asked `isFullscreen`, which that pivot made
permanently false.
- Arrow-key volume was dead in the maximised view: the scroll-deference checked
only `isFullscreenRef`, so the (now hidden but still scrollable) card kept
swallowing Up/Down. Both flags now count as "the video fills the screen".
Measured: 87px of scroll room on the focused card, ArrowDown moves 80 -> 75
and scrolls nothing.
- The maximised view had no way out once the pointer touched the video. Reaching
YouTube's controls means clicking into the cross-origin iframe, which takes
keyboard focus with it, and the re-arm paths (stage mouseleave, window focus)
need the pointer to leave the browser entirely while the stage fills it. So
the exit now lives on screen, in our DOM: a button that un-maximises AND pulls
focus back, re-arming every shortcut.
- WebKit fires only `webkitfullscreenchange`/`webkitFullscreenElement`, so on
Safari/iPadOS YouTube's own fullscreen never registered — no overlay yield, no
focus reclaim. One `fullscreenEl()` reader, both event spellings.
- The stage claimed `z-index: 9999`, the glass tuner's reserved level, for a job
that only needs to beat the modal chrome it is nested in (its siblings top out
at z-menu). Dropped to rail-level; nothing escapes the modal's stacking
context either way.
- `inset: 0` already sizes a fixed layer — the inherited `100vw`/`100vh`
over-constrained it, which is how a classic scrollbar gets a horizontal
overflow and a mobile URL bar hides the bottom edge (YouTube's control bar).
- The shortcut hint still promised "F: fullscreen" in both locales.
Backend, both "the fix stopped one layer short":
- The startup HLS sweep was awaited inside lifespan, so uvicorn still served
nothing until it finished — a thread doesn't help when nothing is listening
yet. Fire-and-forget task instead, cancelled on shutdown. Measured with 200
planted segments: "Application startup complete" now precedes "swept 1".
- An RSS poll where every channel failed returned normally, so the scheduler
recorded `ok` with the outage buried in the summary string. `failed == total`
now raises: a run that reached nothing is a failed run.
Suites: backend 147 -> 150.
UAT found a dead end: F -> YouTube's fullscreen button -> Esc left the player
maximised with no way back, and a further F produced a second, control-less
fullscreen with the wheel driving YouTube's own volume box.
Measured cause: reaching YouTube's control bar means clicking INTO the player,
which moves keyboard focus into the cross-origin iframe — and it stays there.
Our window-level shortcuts then never fire (document.activeElement === IFRAME),
so F went to YouTube instead of toggling our maximise.
Fix: on fullscreenchange, when fullscreen ends, focus the modal card again.
Verified in real Chrome, step by step:
- F -> maximised, no browser lock, focus on our card
- YouTube's own FS button -> real fullscreen (innerHeight 889 -> 1024)
- leaving fullscreen -> focus back on our card (was: still the iframe)
- F -> back to the normal modal view (was: a second fullscreen with no controls)
Root cause, measured in Chrome/Brave/Firefox alike (so: spec behaviour, not a
browser bug): a cross-origin embed reads its fullscreen state from ITS OWN
document. While we hold the browser's fullscreen lock — on our wrapper OR on the
iframe element — the YouTube player never learns it is fullscreen, so its own
fullscreen button stays in the "enter" state and clicking it changes nothing
visible. Every other YouTube control works, which is exactly what the user saw.
So we stop taking the lock: F now toggles a CSS layer (`player-stage--max`) that
fills the viewport. The page stays non-fullscreen, so the embed's own fullscreen
button behaves natively, and our own overlays and shortcuts keep working because
our DOM is what's on screen. Escape steps out of maximise before closing.
Verified end to end in real Chrome:
- F -> stage 1920x889, document.fullscreenElement null (no lock taken)
- YouTube's own fullscreen button -> real fullscreen (innerHeight 889 -> 1024,
fullscreenElement becomes the IFRAME) and its icon flips to "exit"
- clicking it again -> back to the maximised view, our class still applied
- wheel volume while maximised: 100 -> 85, with the level flash visible
Drops the "YouTube fullscreen" toolbar button added earlier today: with the lock
gone, YouTube's own button does that job correctly.
The reported bug: after F, the embed's own fullscreen button is dead. Root cause
measured in Chrome — the browser's fullscreen lock sits on OUR wrapper, so
YouTube's button would need a nested request from a cross-origin frame. Handing
the lock to the iframe fixes it, but `iframe.requestFullscreen()` only resolves
from a CLICK (from a key press the promise stays pending forever, and awaiting
it spends the activation so a fallback is denied too).
So: F keeps fullscreening our wrapper (unchanged, our overlays stay visible) and
a new toolbar button hands the lock to the iframe — verified in real Chrome:
document.fullscreenElement is the IFRAME at 1920x1024, i.e. a plain YouTube
fullscreen where its own controls work.
Round-6 review findings, all fixed:
- one _rate_limiter + one _cancel_poll shared by the yt-dlp hook and run_ffmpeg
(was three hand-rolled throttles; cancel latency differed 2s vs 1s)
- stepVolume takes {delta, fallback} — two adjacent number args were silently
transposable
- volume gestures before the player is ready are honoured instead of dropped
- normalizeVolume's fallback is typed unknown (its guard was unreachable) and
applyVolume takes a number again
- the throttle tests inject a clock instead of patching global time.monotonic
- run_ffmpeg stops the process from ONE exit path (`except BaseException`), so
an exception out of on_progress (a DB write) can no longer orphan a live
ffmpeg after a 10s join on its pipes; _stop is now a no-op on a dead process
- both run_ffmpeg callbacks are throttled to ~1s (they were a DB round-trip per
output line: ~10^5 queries on a long re-encode), mirroring the download hook
- volume arithmetic extracted to lib/playerVolume with unit tests; a corrupt
level now falls back to the LAST GOOD one instead of full blast, and the
sanitising happens where the stored value enters
- RSS is back to two except clauses (the shared tail already sits after the try)
- new tests: callback-exception cleanup, the two throttles; the fake Popen grew
poll() and its wait count is now asserted
Mutation-checked: each new group goes red when its fix is reverted.
- Feed memoizes onClose (like Playlists already did): the inline closure re-ran
PlayerModal's keydown effect on every Feed render, which since the debounce
landed also flushed the volume write and re-stole focus
- the player reads its volume with readAccountMerged again — a partial stored
object made the level undefined -> NaN -> a persisted null; applyVolume also
refuses a non-finite level outright
- that read moved into a lazy useState initializer (was running per render)
- the two RSS except branches share one tail, so a counter can't drift again
- run_ffmpeg tests cover the SIGTERM->SIGKILL escalation and the lingering-
process path; dropped an assertion that only restated the fixture
- storage.ts documents the actual { volume } shape (0 IS muted)
- the sweep guard anchors the rating_key to digits: the round-2 widening had
degenerated to "anything ending in _<digits>" (backup_2024, release_10)
- RSS counts apply-side failures too, so a read-only database no longer reports
a wholly failed poll as "ok — new=0, failed=0"
- the player reads/writes its volume directly (readAccount/writeAccount): the
persisted-object hook rendered nothing and cost a second write per settle
- new tests: the sweep guard's accept/reject table, and run_ffmpeg's threading
(drain, cancel while silent, stall watchdog, stderr tail on a nonzero exit)
- the breaker sentinel is checked one way (isinstance) at all four sites
- run_rss_poll is typed dict[str, int]
All three new test groups were mutation-checked: reverting each fix turns them
red (or, for the cancel/stall pair, hangs — which is the bug itself).
- the volume keys no longer defer to a scrollable card while in fullscreen
(mirrored into a ref: the keydown handler is bound once and state would be stale)
- the debounced volume flush writes straight to storage; persisting inside a
setState updater is not guaranteed to run for an unmounting component
- the HLS sweep also matches the original {key}_{start} directory naming, which
is what the oldest leftovers on disk actually use
- run_rss_poll returns {new, failed} so an egress outage stops rendering as
"ok — 0" in the scheduler card and the audit log; /api/sync/rss reports it too
- drop the unused poll_rss_channel (it silently gained a new exception)
- _Breaker.run is generic, so a call site keeps its item-id type
- test helper instead of the generator-throw idiom
- HLS sweep only deletes directories matching the session-name shape; the root
is admin-configurable and may be a shared path
- playlist unwrap picks the first entry that actually downloaded, not entries[0]
- concat quoting keeps backslashes literal (ffmpeg treats them so inside '')
- ArrowUp/Down defer while the focused element can still scroll that way
- the staging fallback skips yt-dlp working files (.part-Frag/.ytdl/.temp/.fNNN)
- the boot HLS sweep runs off the event loop
- volume persistence is debounced (was a setItem per wheel notch) and a spin no
longer loses notches to the iframe's lagging getVolume
- _Breaker.run owns the whole open/call/record protocol; four call sites shrink
- should_prune extracted and unit-tested, plus RSS error-vs-empty tests
- the worker exits non-zero when the schema never lands
- the interaction overlay yields fully in fullscreen: YouTube only reveals its
control bar while the iframe itself sees the mouse, so after pressing F the
native fullscreen button was unreachable
- remember the volume per account (a YT.Player is created per video and always
starts at 100), plus ArrowUp/ArrowDown volume keys that work in fullscreen
- Ctrl/Cmd+wheel falls through to the browser's zoom instead of the volume
Three player/overlay interaction fixes (PlexPlayer changes share a file, hence one
commit):
- U-C (Escape double-close): useDismiss's Escape now stopPropagation()s (its document
listener bubbles before a player's window listener, so one Escape closes only the
popover, not the popover AND the player). Modal exports modalCount(); both players'
Escape defers when a Modal is open above them, so Escape closes the dialog, not the
player under it and then the dialog.
- U-3.1.4: PlexPlayer's Space now defers to a focused BUTTON/A (e.g. "Skip intro")
instead of toggling playback — matching PlayerModal.
- U-3.3.12: the audio/subtitle menus used theme-adaptive glass-menu + forced
text-white (white-on-white in light theme); they now use the player's own explicit
dark panel (border-white/15 + bg-neutral-900/95), readable in both themes.
Enable noUncheckedIndexedAccess and fix all 98 call sites it surfaced across 18
files. Every fix is behaviour-preserving — the flag flagged reads TypeScript
couldn't prove in-bounds, all of which were already guarded by a length/index check,
a findIndex result, or a non-empty invariant:
- read-once so a ternary's narrowing sticks (Feed overrides, linkify mention);
- non-null assertion AFTER an existing guard (PlayerModal/VideoEditor queue+cut-list
indexing, modules step, useUndoable stacks) with a comment stating the invariant;
- nullish fallback where undefined is a real possibility (GlassTuner slider ?? def,
ConfigPanel active group ?? [], descriptionLinks id ?? null);
- optional chaining where the entry genuinely can be absent (PlexBrowse IO entry);
- a non-empty tuple type for the RELATIVE_UNITS constant (encodes "always has [0]").
The single highest-leverage fix: PlayerModal's `active` became `queue?.[index] ??
video` (always Video), clearing 34 of the 45 errors in that file at once. Verified:
tsc/eslint/prettier clean, 56 vitest + 34 pytest + 17/17 e2e green (the e2e suite
exercises the feed/player/channel components touched here).
Prettier 3 (pinned), printWidth 100, double quotes — chosen to match the existing
hand-formatting and minimise reflow. This commit is ONLY the mechanical format pass
(`prettier --write`) plus the config/ignore/scripts, isolated so it never pollutes a
feature diff. Verified behaviour-neutral: typecheck, eslint (0 errors), and vitest
all green before and after. See .git-blame-ignore-revs — `git blame` skips this sha.
The max-w-6xl bump was a quality lever (bigger pixel box → higher ABR);
the user prefers the smaller max-w-4xl base back. A user-selectable size
preset stays a future item.
Replace ~48 magic z-index values (z-10..z-[9999] + 2 inline zIndex) with named
tailwind zIndex tokens (base/menu/chrome/paneltab/panel/rail/overlay/popover/
tooltip/tuner). Values are UNCHANGED — a rename, not a renumber — so layering is
identical; the names give one source of truth for the stack.
VideoCard/PlayerModal read openChannel from useNavigationActions (the memo'd
VideoCard subscribes to the STABLE actions context, so a page/channel change
no longer re-renders it); NavSidebar/Header read page/setPage; ChannelPage
reads closeChannel; NotificationsPanel reads setPage. App sheds the matching
props, and Feed/VirtualFeed no longer thread onOpenChannel at all.
Locks the five flows the refactor must not break (feed, channel, player,
settings, nav) so later sprints can prove they changed nothing. Adds a thin
data-testid layer and a dedicated seeded non-demo account; the suite runs on
the baked :8080 stack (authoritative) or :5173. No product-behaviour change.
