Release Notes overlay redesign (scoped via .release-notes-shell)
- Backend exposes release.assets (name/size/download_url) through
UpdateReleaseInfo so the frontend can render real download links.
- New masthead: eyebrow + display-font title + tag/published/pre-release
chip strip + close/external action buttons; opts out of layout.css's
global `header { height: 60px }` and `header::before` accent bar that
were leaking into the overlay's <header>.
- Markdown body: <code> filenames are wrapped in clickable <a> via fuzzy
asset match (exact basename, then same-extension token-overlap), with
per-asset description tooltip and a small download glyph.
- Per-asset description derived from filename pattern (Windows installer
/portable/msi, Linux tarball/AppImage/deb/rpm, macOS dmg/pkg, Android
apk/aab, iOS ipa, generic archives) with i18n keys in en/ru/zh.
- Hide checksum / signature side-files (.sha256/.sha512/.sig/.asc/...).
Settings modal & dashboard polish
- ds-section refresh, rail-channel routing, notif matrix updates.
- Dashboard customize panel + per-account layout updates.
- New docs/settings-modal-redesign.html design reference.
Streams / targets / color-strip
- Stream cards rewrite (cards.css, streams.css, streams.ts).
- Composite stream + metrics history adjustments.
- WLED target processor + color-strip pipeline refinements.
- Color-strip WS source streamer touch-ups.
Misc
- Perf charts overhaul; tabular game-integration / HA / MQTT / weather
source cards; donation/sync-clocks/scene-presets minor polish.
- New i18n keys across en/ru/zh.
Test infrastructure
- conftest pre-creates the test DB so main.py's legacy-data migration
doesn't shovel the user's production DB into the test temp dir.
- test_preferences_notifications wipes its own setting at the start of
the defaults test (was relying on isolation it never enforced).
Pre-commit gates: ruff clean, tsc clean, npm run build clean,
pytest 899/899 passing.
Surface device connection state changes (configured target online/offline)
and discovery events (new WLED on LAN, new serial port, devices that
disappear) through a configurable per-event channel matrix:
none / snack / OS / both.
- Backend: long-running mDNS browser + 10 s serial poller in
core/devices/discovery_watcher.py, gated by user pref. Reuses the
existing device_health_changed event for online/offline transitions.
New GET/PUT /api/v1/preferences/notifications endpoint with Pydantic v2
schema (channel matrix + background-discovery flag + grace/debounce).
13 new tests, full suite still 899 passing.
- Frontend: features/notifications-watcher.ts with startup-grace +
flap-debounce + bulk-coalesce pipeline. Web Notifications API for the
OS channel (no platform-specific code, works in PWA shell).
New "Notifications" tab in Settings with 4 IconSelect rows + bg toggle
+ permission row + test button. en/ru/zh translations.
Defaults: device_offline=both (urgent), online/discovered=snack, lost=none,
background discovery on. Already-configured devices are filtered from
discovery events to avoid double-notifications.
