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.
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.
Add components/Overlay.tsx (portals to <body>) and route the in-tree full-screen/
floating holdouts through it — ChatDock, OnboardingWizard, GlassTuner — so they
escape any ancestor stacking context (mask/transform/backdrop-filter) instead of
relying on a bare high z-index. Toaster stays in-tree (it's content-column-scoped
by design, outside the masked scroller); Welcome is a page, not an overlay.
Feed, VideoCard, Sidebar, PlayerModal, Channels, Stats, SettingsPanel,
OnboardingWizard, NotificationCenter, Toaster, ErrorBoundary and the relativeTime
helper are now fully translated in Hungarian, English and German, each with its own
locale area file (auto-loaded). Key parity verified across all three languages.
After read access is granted the wizard now imports the user's YouTube
subscriptions automatically (with a "Building your feed…" progress state), so a
new user lands on a populated feed — channels already in the shared catalog show
up instantly, new ones backfill in the background. The empty feed now prompts
users without read access to set up via the wizard instead of a bare message.
After the clean name/email sign-in, a wizard walks the user through granting
YouTube read (then optionally write) one step at a time, each with a plain
rationale and an up-front heads-up about Google's "unverified app" screen.
The visible step is derived from the granted scopes (can_read/can_write) so the
flow resumes correctly across the full-page consent redirect; it's dismissible
and reopenable from Settings -> Account, which now lists read and write as
separate, individually-grantable access rows.
