-This release ships the **Lumenworks studio-console** — a top-to-bottom WebUI redesign — plus a customizable per-account dashboard, a server-shutdown control, and a handful of dark/light/narrow-screen polish fixes.
+This release adds **device-event notifications** (snack + Web Notifications), a **daylight/timezone-aware streaming pipeline** with a new camera engine, a **redesigned Targets surface** built on the dashboard's mod-card system, a **tighter LED hot path** with allocation-free per-frame work, and a **revamped Release Notes overlay** with clickable asset downloads. Plus a wide pass of modal, toolbar, and settings polish across the WebUI.
 
 ### Features
-- **Lumenworks studio-console WebUI redesign** — new visual language across the entire WebUI: studio-console layout, refined typography, accent system, and motion. ([539e431](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/539e431))
-- Extend the Lumenworks treatment to the **Inputs**, **Integrations**, and **Graph** tabs so the redesign is consistent across all top-level views. ([b43e1cf](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/b43e1cf))
-- **Per-account customizable dashboard** with a slide-in configuration panel — each user can pick their own widget layout, persisted per account. ([56853b7](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/56853b7))
-- Dashboard polish: richer performance strip, transport-bar controls, and additional readouts on the main view. ([e5a2af9](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/e5a2af9))
-- Item-card restyle with hover-driven performance tooltips and a configurable FPS ceiling. ([70c95d1](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/70c95d1))
-- **Live card-color picker** — pick a custom color per card and see it apply instantly; default preset now uses the base palette. Monotonic uptime ticker no longer jitters on clock adjustments. ([e0ff40f](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/e0ff40f))
-- **Server shutdown action** exposed in the WebUI, backed by a public `cancel_task` lifecycle method so long-running tasks unwind cleanly. ([3f80ef2](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/3f80ef2))
+- **Device event notifications** — configurable per-event channel matrix (none / snack / OS / both) for target online/offline, new WLED/serial discovery, and devices going missing. Backed by a long-running mDNS browser + 10 s serial poller, a startup-grace / flap-debounce / bulk-coalesce pipeline, and a new Notifications tab in Settings (en/ru/zh). ([8aa3a32](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/8aa3a32))
+- **Daylight + timezone streaming** — new `daylight_settings` module and `daylight-tz` frontend helper expand the daylight stream's behavior; capture path additions land alongside a new **camera engine** test suite. ([fdac26b](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/fdac26b))
+- **Targets cards migrated to the mod-card system** — LED targets and HA Light targets now share the dashboard's instrument-readout vocabulary (mod-head / mod-leds / mod-metrics / mod-foot, kebab menu, badges, chips, patch indicator). LED preview, FPS sparkline, and pipeline metrics preserved via an `extraHtml` escape hatch. ([233b463](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/233b463))
+- **Target pipeline as a compact strip + chip row** — drops the legacy "Pipeline details" collapsible block; an always-visible 4 px segmented timing bar (extract / map / smooth / send for video, read / fft / render / send for audio) sits above an inline chip row showing total ms / frames / keepalives, animating smoothly between samples. ([51eebf2](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/51eebf2))
+- **Targets metrics aligned with the dashboard** — FPS sparkline now lives inside the FPS cell, Uptime gets a clock icon, Errors gets ok/warning by count, FPS readout adopts the dashboard `current/target avg N.N` shape, and the grid sizes so values like `1m 43s` no longer truncate at typical desktop widths. ([9067db2](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/9067db2))
+- **Release Notes overlay v2** — new masthead with display-font title, tag/published/pre-release chip strip, and close/external actions; markdown body fuzzy-matches `<code>` filenames to release assets and renders clickable download links with per-asset descriptions (Windows installer/portable/msi, Linux tarball/AppImage/deb/rpm, macOS dmg/pkg, Android apk/aab, iOS ipa). Checksum/signature side-files are hidden. ([9d4a534](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/9d4a534))
+- **Tutorials expansion** — sub-tab switching, breadcrumb header, and prepare/switchSubTab hooks let tours open/close the dashboard customize panel and resolve targets behind sub-tabs; new steps for integrations, dashboard customize panel (presets / global / sections / perf cells), targets, scenes, and sync-clocks (en/ru/zh). ([797b806](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/797b806))
+- **Cards / settings / modal / toolbar polish** — reworked mod-card colors, sections, channel-stripe styling, hairline borders, and signal-flow animation on running cards; multiselect bulk toolbar gets explicit Select-all / Deselect-all icons with luxury-gradient toolbar styling; Settings tabs are now icon-only (no overflow at any locale); modal exit animation gains symmetric fadeOut + slideDown keyframes with reduced-motion support; locale picker collapses to EN / RU / ZH; snack toast adopts a glass background with per-type accent. ([a56569b](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/a56569b))
+- **Suppress browser auto-open on Windows login** — when "Start with Windows" is enabled, the autostart shortcut now passes `--autostart` so the WebUI tab no longer pops on every login. Manual launches and the installer's "Launch LedGrab" finish-page action are unchanged. ([de13f44](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/de13f44))
+- **Simpler segment payloads** — `SegmentPayload.start` defaults to 0 and `length` defaults to "the rest of the strip from start". A single segment with only `mode` + `color` now fills the entire strip — no more `length: 9999` magic value clients had to pass. ([1c9acc5](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/1c9acc5))
+- About panel now houses the author + contact details that previously lived in a global app footer, freeing up vertical space across every page (en/ru/zh `donation.about_author` key added). ([816a27d](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/816a27d))
+
+### Performance
+- **LED hot path is allocation-free per-frame**: Adalight gets a dedicated single-worker tx executor, pre-allocated wire buffer, uint8 scratch, and a precomputed header struct; DDP gets a pre-built `struct.Struct` and memoryview emit path; calibration precomputes Phase 3 skip-LED resampling so per-frame work is now `np.take` + in-place blend; the WLED target processor gets a matching tightening. ([797b806](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/797b806))
 
 ### Bug Fixes
-- Channel stripe on item cards now only paints when the card has a custom color or is running — no more stray accents on idle defaults. ([b1ee3c3](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/b1ee3c3))
-- Cards render correctly on pure black and pure white backgrounds, and are decoupled from the animated background so they stay legible regardless of the bg-anim setting. ([dd415e2](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/dd415e2))
-- Single-row header layout and readable sidebar labels at narrow widths — fixes wrapping and label truncation on smaller windows. ([2bae304](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/2bae304))
+- **Audio-source modal preserves device on refresh** — refresh button moved into the label row (no more overflow past the Source panel edge); selection is restored by matching on `(index, loopback)` first with a trimmed-name fallback for OS-side reindexing; the EntitySelect trigger now syncs so the visible label matches the underlying `<select>` in edit mode. ([0980cf4](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/0980cf4))
+- **PWA meta tag** — add the standard `mobile-web-app-capable` tag while keeping the Apple variant for iOS Safari, since Chrome deprecated `apple-mobile-web-app-capable`. ([8e109f3](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/8e109f3))

 ### Development / Internal
 
-#### Chores
-- Harden test isolation, add `.gitignore` rule for stale `src/data/`, and mark the shutdown action done in the task tracker. ([80f01d4](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/80f01d4))
+#### CI/Build
+- Add `workflow_dispatch` and skip lint/test on release commits (release.yml already runs in parallel; manual dispatch covers re-runs on demand). ([033c1f6](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/033c1f6))
+
+#### Tests
+- New `test_camera_engine` suite covers the new capture path. ([fdac26b](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/fdac26b))
+- Adalight + DDP tests cover header format, buffer reuse, non-contiguous input, brightness scaling, RGB/RGBW packets, sequence/PUSH semantics, and multi-packet fragmentation. ([797b806](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/797b806))
+- 13 new tests for the device-event notifications backend (full suite still 899 passing). ([8aa3a32](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/8aa3a32))
+- `conftest` pre-creates the test DB so `main.py`'s legacy-data migration no longer shovels 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). ([9d4a534](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/9d4a534))
+
+#### Tooling
+- `.mcp.json` checked in with code-review-graph MCP server config so the graph tools are available out of the box. ([797b806](https://git.dolgolyov-family.by/alexei.dolgolyov/ledgrab/commit/797b806))
