Per-user opt-in to full-history (deep) backfill so a new user's unique
channels no longer trigger a big shared-quota burst.
- migration 0007: Subscription.deep_requested (default false); seed admins'
existing subscriptions to preserve today's global-backfill behaviour
- run_deep_backfill is now demand-driven: only channels at least one user has
requested are deep-backfilled; recent backfill stays unconditional (cheap)
- estimate_deep_backfill ETA helper (quota-bound) surfaced in /api/sync/my-status
- POST /api/sync/deep-all to opt all my channels in; PATCH channels accepts
deep_requested
- UI: per-channel Full history toggle, Backfill everything action, deep
progress + ETA in Channels header and Settings - Sync
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.
- 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.
Backend: /api/channels (list + PATCH priority/hidden + attach/detach user tags),
user-tag CRUD on /api/tags, /api/sync/my-status (per-user channel sync counts).
Frontend: feed|channels page nav (URL-synced) from the account menu; a slide-in
tabbed Settings panel (Appearance, Notifications=6b sound+duration, Sync status +
actions + admin pause/resume, Account); a channel manager with priority, hide,
per-channel user tags, sync badges and 'view in feed'. Notifications now honor the
configurable sound + auto-dismiss settings.
