Add a light set of the 6 per-scheme backdrops (public/backdrops/light/*.svg) —
soft, pastel-mid, non-figurative washes tuned to each accent so they read through
the light translucent glass. Wire them up centrally:
- App: the backdrop is on whenever bgImage && !perf (was dark-only), so light
gets it too.
- index.css: per-scheme rules are now [data-theme]-qualified — dark uses the dark
set, light the /light/ set; shared cover/fixed size rule for both.
- Settings: the Background image toggle + Image-fade slider work in light now
(removed the dark-only gates); hint no longer says 'dark only'. Trilingual.
The light glass (62% translucent tier) refracts the light backdrop just like dark
refracts its own; one fade slider controls both.
Light theme has no background image, so the adaptive :root glass (94%) rendered
as flat snow-white islands, while the Plex filter rail (still on bg-surface/40)
showed the ambient tint — an inconsistency. Fix centrally, not per-component:
- index.css: one html[data-theme="light"] token override (surface 62 / card 74 /
menu 86) so every .glass* surface is translucent in light and picks up the
ambient tint, like it refracts the backdrop in dark.
- PlexSidebar: bg-surface/40 -> glass, so all filter rails bind to the same token.
One central lever now controls the light-theme glass translucency for the whole app.
Code review (public-repo rule): the GlassTuner + index.css/App.tsx comments named
the prod hostname and dev-process jargon (UAT/HMR/dev ports/epic), which ship in
the public bundle. Genericised the comments — no behaviour change.
Land the UAT-approved backdrop direction as a real feature (replacing the dev
thumbnail prototype):
- 6 generated abstract SVG backdrops in public/backdrops/, one tuned to each
accent scheme (dark, mixed-colour, few light areas). Non-figurative + generated
= repo-safe, tiny, accent-matched.
- New data-backdrop="on" state (dark theme + the setting + not perf) paints the
per-scheme image on <body> (app root now transparent so it shows app-wide and
the glass refracts it) AND switches the glass to its translucent tier (the
user's tuned values: surface 50 / card 60 / scrim 30 / blur 10 / edge 25).
Off / light / perf -> flat colour + solid glass (the readable fallback).
- Settings > Appearance 'Background image' toggle (bgImage pref, dark-only),
trilingual. Flat is the fallback + opt-out.
- Remove the FeedBackdrop prototype + its tuner controls; tuner baseline resynced
to the glass-over-image tier, add a Backdrop-fade slider.
GOTCHA fixed: the dark-mode ambient 'background' shorthand reset background-size
to auto (image rendered un-covered); out-specified it with [data-theme="dark"].
Idea from UAT-2: give the feeds the same 'content behind glass' lift the Plex
detail page gets. New FeedBackdrop paints a faint, slowly-rotating feed thumbnail
as a fixed backdrop on <main> (the proven art-backdrop path — a fixed z:-1 layer
is occluded by the root's opaque bg-bg). Blur = tiny-canvas downscale + cover
upscale (no CSS filter; ytimg is CORS-readable so it uses a data-URL, else raw).
Flat --bg stays as the 'perf mode' look. Behind the GlassTuner toggle + a
Backdrop-fade slider (--feedbg-fade) so it's judged/tuned in UAT before anything
is committed for real.
From UAT: glass reads strongest where there's content behind it, so split the
look into two tiers instead of one global compromise.
- index.css: global :root defaults are now the 'Adaptive' baseline (solid-enough
dark glass for content-less chrome). New .glass-media scope class carries the
UAT-tuned translucent values (blur 10 / surface 50% / card 60% / scrim 30% /
edge 25%) for surfaces that float over real artwork.
- Apply .glass-media to the art-backed Plex detail views (PlexInfo page variant,
PlexShowView, PlexSeasonView) and drop PlexInfo's hard-coded inline 55%
overrides so those panels are scope-driven and consistent (hero no longer
reads solid while the season strips are translucent).
- Two new colour schemes: Starship (deep-space blue, azure accent) and Matrix
(near-black, phosphor green), each with dark+light tokens + swatches.
- Remove the thumbnail-mosaic backdrop (did nothing usefully; its home is the
future 'videos behind glass' phase) — deletes MosaicBackdrop, mosaic vars/CSS,
and the tuner's mosaic controls. GlassTuner presets resynced to the new
baseline (Current / Media / Max-readable).
Foundation for the app-wide glass-consistency epic:
- index.css: every look-driving value (blur/saturate/dark-brightness/panel-card-
menu opacity/border/inset/edge/scrim/ambient + mosaic) is now a CSS custom
property defaulting to the historical hard-coded value — one-place tunable, no
visual change until a value is bumped.
- GlassTuner.tsx: dev-only (localhost-gated) always-on corner panel that live-
drives those vars, with treatment presets (Adaptive/Gradient+/Edge+scrim),
per-scheme palette editor, muted thumbnail-mosaic toggle, localStorage persist,
and Copy-CSS export. Deleted once the tuned finals are baked in.
- MosaicBackdrop.tsx: opt-in muted (blur+darken+desaturate) mosaic of on-screen
thumbnails so dark glass has real content to refract.
Adds player-modal shortcuts and keeps keyboard focus on the modal (not the
cross-origin player iframe) on open and on player-ready, so they work until you
click into YouTube's native controls:
- F: toggle fullscreen (the player stage element, so the volume flash stays
visible; a :fullscreen CSS rule drops the 16:9 letterbox). Esc in fullscreen
exits fullscreen only, without also closing the modal.
- Space: play/pause (ignored while a button/input is focused).
- Scroll wheel over the video: volume up/down with an auto-fading volume-bar
overlay. A transparent interaction layer over the iframe catches the wheel
(the cross-origin iframe otherwise swallows it) and maps click to play/pause;
it leaves the bottom strip uncovered so YouTube's native control bar (seek /
settings / captions / fullscreen) stays usable, and is hidden on an embed
error so the 'Open on YouTube' CTA stays clickable.

The ring-based flash relied on ring-accent and a CSS transition that never
restarted on a repeat message, so it was effectively invisible. Replace it with
a keyed inset-glow overlay (animation replays on every flash counter bump, and
inset shadow isn't clipped by the window's overflow-hidden) — flashes whether
the window is expanded, freshly auto-opened, or minimised.
Toasts rose top-right, far from the notification bell which now lives bottom-left.
Anchor them bottom-left inside the content column (clears the sidebar at any width),
newest nearest the bell. Add a ~50% white border in dark mode so they stand out off
the conventional top-right spot.
Dark glass looked nearly flat because the blurred backdrop is itself dark. Add a
brightness lift to backdrop-filter in dark mode for .glass/.glass-menu so the frosted
sheen reads even over dark surfaces (over colourful content it just looks richer).
Perf-mode still disables the blur (later rule wins).
Floating menus hover over undimmed content (no backdrop scrim like dialogs), so the
frosted .glass (78%) let the content bleed through and hurt readability. Add a near-opaque
.glass-menu (surface 92%, keeps blur) and use it for the account, language, notification
and add-to-playlist popovers. Dialogs/chrome keep the frostier .glass (they sit over a dark
scrim / the ambient bg). perf-mode disables its blur too.
The dark-mode experiment made .glass globally more translucent (surface 66%), which
also hit content-overlapping surfaces like the account popover — text became hard to
read over the feed behind it. Drop that override so .glass is back to the readable 78%
everywhere; keep the richer dark ambient (harmless to readability). Docked chrome loses
the marginal extra frost (which was barely noticeable anyway).
In dark mode the faint accent pools left the docked frosted chrome (nav/header) looking
flat — no content behind it to refract, unlike dialogs over the feed. Boost the dark-mode
ambient pools and make .glass a bit more translucent there so the chrome reads as glass
near the accent pools. Light mode unchanged. The full app-wide dark effect still needs
Phase 2 (ambient content/mosaic), deferred.
Apply the real frosted .glass surface (blur) to the few large chrome surfaces — the nav
sidebar, the header and all Modal-based dialogs (was glass-card / plain surfaces) — and
enrich the ambient backdrop a touch (three soft accent pools) so the glass has more to
refract app-wide. Popovers (notifications, language, account, add-to-playlist) were
already glass. Bulk feed cards stay glass-card (no per-card blur) for performance; the
existing perf-mode still disables blur. Phase 2 (ambient thumbnail mosaic / bg image +
toggle) deferred to end-of-project polish.
Three low-risk wins for large filtered feeds:
- content-visibility:auto on cards (.cv-card/.cv-row) so the browser skips
layout/paint for off-screen cards; contain-intrinsic-size keeps the scrollbar
stable and is remembered per card after first render.
- memo(VideoCard) + stable onState/onChannelFilter callbacks (onState reads the
loaded list via a ref) so appending a page only renders the ~60 new cards
instead of reconciling every card already on screen.
- Prefetch the next page earlier (sentinel rootMargin 800px → 1500px) so the
'Loading more…' flash is far less likely during fast scrolling.
backdrop-filter blur does work here; the previous 94% opacity made .glass nearly
solid so the blurred backdrop never showed. Dial back to 82% with a strong blur so
overlays read as frosted glass again, while staying less see-through than the old
72% that made the account menu look too transparent.
Evidence (sharp video behind overlays) shows backdrop-filter is a no-op here, most
likely because browser hardware acceleration is off — so the glass relied on a blur
that never rendered. Lean on opacity instead (94% surface) so overlay menus/panels
read as frosted glass regardless of GPU; keep the blur as a bonus when available.
Revert the settings backdrop to a plain dim scrim (no whole-page blur) and make the
header a solid bar (no backdrop-filter ancestor).
- Increase .glass blur (32px) so overlay menus (account) read as proper frosted glass.
- Blur the settings modal backdrop (overlay backdrop-blur) so the panel reliably
frosts the content behind it instead of showing a sharp video through.
- Remove the now-redundant header buttons (dark/light, color scheme, grid/list) —
they live in Settings → Appearance. Header keeps search, sync, bell, account.
Video cards / channel rows / sidebar widgets render in bulk over a solid background
where backdrop blur adds little but is GPU-expensive and triggers forced reflow
(browser perf 'Violation' logs). Keep translucency + depth; reserve blur for the few
.glass overlay surfaces (menus, panels, toasts, tooltips).
- Tooltip: render in a portal with fixed positioning + edge-flip so hints are never
clipped by overflow/stacking ancestors (fixes mispositioned/hidden bubbles app-wide).
- Glass: raise opacity so overlay menus/panels stay readable over content.
- SettingsPanel: vertical tab rail (no wrapping/jumping), content grid-stacked so the
panel sizes to the tallest tab (stable height) and floats to its content height.
- Notifications: the test toast is now a normal auto-dismissing toast (with countdown
bar) that also plays the sound via a new force-sound flag.
- Channel manager: explain priority/tags/hide and what 'Sync subscriptions' does;
add a 'Channel priority' feed sort so priority is actually meaningful.
- Add a theme-aware glass surface system (.glass/.glass-card + ambient backdrop,
performance-mode opt-out) and apply it across panels, popovers, toasts, cards,
sidebar widgets, channel rows, video cards and login.
- SettingsPanel: slide in/out animation, glass styling, wrapping pill tabs (no
horizontal scrollbar) with a prominent active state.
- Notifications: auto-dismiss can be switched off (stays until closed); the test
notification now also triggers the alert sound; resume a suspended AudioContext.
- Add an app-wide, toggleable hint/tooltip system (lib/hints + Tooltip) and wire
hints across the settings and channel-manager surfaces; persisted per account.
- NotificationCenter closes on outside click (document listener, not an overlay
that the blurred header trapped) and no longer needs a second bell click.
- Toasts show a level-colored countdown bar and auto-dismiss faster (6s default).
- Hidden-video notifications carry structured meta so the center offers an in-app
'Find in feed' (jump to that channel's hidden videos) and a one-click 'Unhide',
working even after a reload when the live Undo callback is gone.
- Hidden view shows an Unhide action (eye icon) instead of Hide
- Upload-date filter: From/To date range (inclusive); feed shows only videos
published in that window (backend published_after / published_before)
- New sort options: Name (A-Z) and Channel subscribers, alongside date/views/
duration/shuffle
- Native controls follow the theme via color-scheme (dark date picker)
- Vite + React + TS + Tailwind SPA served by FastAPI (multi-stage Docker build)
- Four color schemes (Midnight default, Forest, Slate, YouTube) x dark/light,
adjustable text size; persisted to user preferences and localStorage
- Header search, grid/list toggle, theme menu; sidebar filters (show state,
sort, include Shorts/live, language + topic tag chips with any/all matching)
- Infinite-scroll feed of video cards; click opens youtube.com in a new tab;
per-video watched / saved / hidden actions with optimistic updates
- SPA fallback routing; login screen for unauthenticated users
