feat: add viewer metrics and dynamic category display to playback overlay

- Live streams: show viewer count and current category inline next to LIVE indicator
- VODs: display clapperboard badge, total view count, and chapter-based category
- Chapter-based category updates automatically based on playback position
- Chapters are preloaded on VOD start; fallback category is "Unbekannt" if missing
- Add icons: EyeIcon, GamepadIcon, ClapperboardIcon

 2. Bridge-Methode in `src/preload/index.ts`
 3. Typ-Deklaration in `src/renderer/src/types/t4sd.d.ts`
 
+### Zwei Playback-Kontexte
+
+**1. ChannelScreen-Playback** (Live + VOD, X-Button oder „Du folgst"):
+- Nutzer navigiert zur ChannelScreen → drückt „▶ Live ansehen" oder wählt einen VOD
+- ChannelScreen hält eigenen `hlsPayload`-State, eigenen `videoRef`, eigene PlaybackOverlay
+- VOD-Features: Resume, Kapitel-Panel, Position-Tracking
+
+**2. Globaler AppShell-Overlay** (Direkt-Start, A-Button in BrowseScreen/StreamListScreen/CategoryScreen):
+- Nutzer drückt A auf einer Stream-Karte → `onStartLive(ch)` → AppShell ruft `startLive()` direkt auf
+- AppShell hält `liveChannel`, `liveHlsPayload`, `livePlayState`, `liveVideoRef`
+- `isGlobalPlaybackInitiated` Ref verhindert, dass ChannelScreen-IPC-Events den globalen Overlay aktivieren
+- Während Playback: `hasFocus={false}` für alle Browse-Screens → keine Tastenkonflikte
+- AppShell-eigener Keydown-Handler: Escape=Stop, Enter=Pause, Pfeile=Seek
+- Nur Live-Streams (kein VOD, kein Resume, kein Position-Tracking)
+
+### Playback-Architektur (hls.js im Renderer)
+Video läuft als HTML5 `<video>` Element innerhalb des Electron-Fensters — **kein externer mpv-Prozess**.
+
+**VideoPlayer-Initialisierung (kritisch):**
+1. `hls.attachMedia(video)` — zuerst Media-Kontext aufbauen
+2. Im `MEDIA_ATTACHED`-Event: `hls.loadSource(hlsUrl)` — dann erst Source laden
+3. Im `MANIFEST_PARSED`-Event: `video.play()` — jetzt ist MediaSource bereit
+- **Reihenfolge wichtig:** `loadSource` vor `attachMedia` → MANIFEST_PARSED feuert bevor MSE bereit → `play()` wirft `NotSupportedError: The element has no supported sources`
+- **CSP:** `media-src 'self' blob:` in `src/renderer/index.html` — hls.js braucht `blob:` für MediaSource
+
+**Imperative Handle** — ChannelScreen / AppShell halten `videoRef = useRef<VideoPlayerHandle>()`:
+- `videoRef.current.seek(delta)` — relativer Seek (Sekunden)
+- `videoRef.current.seekTo(abs)` — absoluter Seek
+- `videoRef.current.pause()` / `.play()` / `.togglePause()`
+- `videoRef.current.stop()` — zerstört hls.js-Instanz, leert `<video>`
+- `videoRef.current.getCurrentTime()` — aktuell abgespielte Position (synchron)
+
+**Warum dieser Ansatz:** Früherer Ansatz mit externem mpv-Fullscreen-Fenster wurde vom OS-Windowmanager (Gamescope auf Steam Deck) immer über das Electron-Fenster gelegt. CSS `z-index` wirkt nur innerhalb eines Dokuments, nicht auf OS-Fensterebene. Die Lösung: Video und Overlay im selben Rendering-Kontext halten.
+
+### Kapitel-Panel during Playback
+Wenn der User während der Wiedergabe das Kapitel-Panel öffnet (Y-Taste), wird das Video **pausiert** (nicht gestoppt). Nach Kapitelwahl: `seekTo(chapter.positionSeconds)` + `play()`. Nach Schließen ohne Auswahl: `play()` (falls vorher playing).
+
 ### Gamepad Dual-Path
 - **Linux/Gaming-Mode:** `src/main/input/gamepadReader.ts` liest `/dev/input/js*` direkt (Chromium Gamepad API funktioniert nicht im Flatpak-Sandbox ohne udev)
 - **Windows/Dev:** `src/renderer/src/input/gamepad.ts` nutzt `navigator.getGamepads()` via rAF-Loop
 - Beide Pfade erzeugen synthetische `KeyboardEvent('keydown')`. Alle UI-Komponenten reagieren nur auf Key-Events — kein Gamepad-Code in Screens.
 - Button-Mapping: A=Enter, B=Escape, X=x, Y=y, LB=l1, RB=r1, LT=l2, RT=r2, DPad=Arrows
 
-### Live-VOD- und fMP4-Snapshot-Logik
+### A-Button-Verhalten je Screen
-`PlaybackService` unterscheidet vor dem VOD-Start zwischen abgeschlossenen VODs und laufenden Live-VODs:
+| Screen | A-Button | X-Button |
-- `inspectVodPlaylist()` prüft das HLS-Manifest auf `#EXT-X-MAP`, `#EXT-X-PLAYLIST-TYPE` und `#EXT-X-ENDLIST`
+|---|---|---|
-- **Laufende Live-VODs** kommen von Twitch oft als offene `EVENT`-/DVR-Playlist zurück; diese würde mpv sonst wie einen Live-Stream behandeln und am Live-Rand starten
+| FollowingScreen | Kanalseite öffnen | — |
-- **fMP4-VODs** sind zusätzlich für HLS-Seeks im FFmpeg/mpv-Demuxer unzuverlässig
+| BrowseScreen (Shelf) | Stream direkt starten (AppShell-Overlay) | Kanalseite öffnen |
-
+| StreamListScreen | Stream direkt starten (AppShell-Overlay) | Kanalseite öffnen |
-Workaround in `src/main/playback/hlsTrimmer.ts`:
+| CategoryScreen | Stream direkt starten (AppShell-Overlay) | Kanalseite öffnen |
-- erzeugt aus der aktuellen Twitch-Playlist einen lokalen statischen Snapshot ab Zielsegment
+| ChannelScreen | Live-Stream starten / Bestätigen | — |
-- setzt immer `#EXT-X-PLAYLIST-TYPE:VOD`
-- setzt immer `#EXT-X-ENDLIST`
-- serviert die Playlist via lokalem HTTP-Server (zufälliger Port auf `127.0.0.1`)
-- mpv lädt neue Snapshots via `loadfile replace`
-
-Wichtig:
-- Warum HTTP statt `file://`: FFmpeg's Protokoll-Whitelist blockiert HTTPS-Subrequests von file://-HLS-Playlists
-- `streamlink --stream-url` liefert bei laufenden VODs nur die rohe Twitch-DVR-URL; erst der lokale Snapshot macht daraus ein statisches VOD
-- `PlaybackService` hält eine **absolute VOD-Zeitachse** über `playbackOffsetSeconds` + `lastKnownAbsolutePositionSeconds`, damit Kapitelwahl, Resume und Folge-Seeks nicht auf die lokale Zeit des Snapshots driften
-- Reload-Races werden über `seekGeneration` / `loadGeneration` abgefedert, damit alte `time-pos`-Events keine falschen Offsets in die History schreiben
-
-### mpv JSON-IPC
-`src/main/playback/mpvController.ts` kommuniziert via Unix-Socket (`/tmp/twitch4sd-mpv.sock`) oder Windows Named Pipe (`\\.\pipe\twitch4sd-mpv`). Wichtig:
-- Verbindung wird mit 12 Retries × 250ms hergestellt (mpv braucht Zeit zum Starten)
-- `observeTimePos()` abonniert `time-pos`-Events; falls in 10s kein Event kommt → Fallback auf `pollTimePos()` (Intervall-Polling)
-- `playback-restart` markiert nach `loadfile` den aktiven Reload als abgeschlossen; bei klassischen TS-VODs triggert es außerdem den initialen Resume-Seek
 
 ### VOD vs. Live Playback
-- **Live:** `streamlink --player mpv --player-args '...'` — Streamlink managed mpv intern. Kein IPC nötig (kein Seeking bei Live).
+- **Live:** `streamlink --stream-url twitch.tv/<login> best` → HLS-URL → hls.js spielt Live-Playlist nativ
-- **VOD:** `streamlink --stream-url` liefert eine HLS-URL → mpv wird **direkt** mit `--input-ipc-server` gespawnt. Ermöglicht Seeking + Position-Tracking.
+- **VOD:** `streamlink --stream-url twitch.tv/videos/<id> best` → HLS-URL → hls.js seeked zu `startPosition` via `video.currentTime`
-- **Laufendes Live-VOD:** Die von Streamlink gelieferte URL ist oft eine offene `index-dvr.m3u8` (`EVENT`, ohne `ENDLIST`). Diese darf nicht direkt an mpv gehen, sondern wird zuerst lokal als Snapshot eingefroren.
+- **Resume:** `history.getPosition(vodId)` im Main-Prozess → als `startPosition` im `playback:hls-url` Event → `VideoPlayer` seeked nach MANIFEST_PARSED
-- **Geschlossenes fMP4-VOD:** Seeks laufen ueber Snapshot-Reload statt mpv-internem HLS-Seek.
+
-- Reason: Piped Streams (streamlink mit stdout) sind nicht seekable.
+### Position-Tracking
+`VideoPlayer` meldet alle 5s via `window.t4sd.playback.reportPosition(vodId, currentTime, durationSeconds)` → Main → `historyRepo.updatePosition()` + `markCompleted()` (bei >95% Fortschritt). Nur für VODs (nicht Live).

-
-> Stand: **2026-04-09 (Session 5)**. Diese Datei dient als Übergabe zwischen Sessions.
-> **Lies zuerst:** diese Datei + `todo.md` + `plan.md`.
-
-**Aktueller Stand:** Phase 0–5.6 abgeschlossen & verifiziert. Phase 6 (Flatpak-Packaging): Manifest + Hilfs-Dateien geschrieben, wartet auf User-Verifikation in WSL2 + Steam Deck.
-
----
-
-## Bereits abgeschlossen
-
-### ✅ Phase 0 — Projekt-Skelett
-### ✅ Phase 1 — Twitch OAuth Device Code Flow
-### ✅ Phase 2 — Twitch Helix-Client + Sidebar-Layout
-Alle drei End-to-End verifiziert 2026-04-07.
-
----
-
-### ✅ Phase 3 — Streamlink + mpv (Live-Wiedergabe)
-
-Verifiziert 2026-04-08.
-
-#### Architektur-Entscheidungen:
-- `--twitch-api-header` wird **nicht** übergeben — Twitch lehnt den Device-Code-Token für
-  streamlinks interne GQL-API ab. Öffentliche Streams funktionieren ohne Auth-Header.
-- `resolveMpvBin()` löst den mpv-Pfad explizit auf (`C:\Program Files\MPV Player\mpv.exe`),
-  da Electron den User-PATH nicht vollständig erbt.
-- `--twitch-disable-ads` ist von streamlink deaktiviert worden (deprecated) — kein Ad-Bypass
-  im Moment. Post-MVP-Problem.
-
----
-
-### ✅ Phase 4 — VOD-Browsing + -Wiedergabe
-
-Verifiziert 2026-04-08.
-
-#### Architektur-Entscheidungen:
-- **VODs:** streamlink `--stream-url` liefert HLS-URL → mpv wird **direkt** mit der URL
-  gespawnt (nicht via `--player`-Flag). Grund: Piped-Streams sind nicht seekable.
-  Direktes mpv-Spawnen ermöglicht Seeking + funktionierendes IPC.
-- **Live-Streams:** weiterhin via `--player mpv --player-args "--fullscreen"`. Kein IPC
-  nötig (kein Seeking, kein Position-Tracking bei Live).
-- VOD-Shelf im `ChannelScreen` (untere Hälfte, horizontal, oberer Hero-Bereich fix).
-  Navigation: ↓ → Shelf, ←/→ zwischen VODs, ↑ → zurück, Enter → abspielen.
-
----
-
-### ✅ Phase 5 — Lokaler VOD-Verlauf (Resume)
-
-Verifiziert 2026-04-08.
-
-#### Neue Dateien:
-- `src/main/store/db.ts` — SQLite via better-sqlite3, WAL-Modus, Migration
-- `src/main/store/historyRepo.ts` — `upsertVod`, `updatePosition`, `markCompleted`,
-  `getPosition`, `getProgressMap`
-
-#### Architektur-Entscheidungen:
-- mpv IPC funktioniert jetzt zuverlässig (da mpv direkt gespawnt wird).
-  `MpvController.observeTimePos()` parst eingehende JSON-Lines, Throttling auf 5s.
-- Resume-Position wird beim `startVod()`-Aufruf automatisch aus DB gelesen.
-- Auto-Complete bei >95% Fortschritt.
-- `„Continue Watching"-Reihe` wurde bewusst weggelassen (vom User nicht gewünscht).
-- VOD-Karte zeigt: Fortschrittsbalken (lila), `0:16 von 6:22`, `Vor X Min.`,
-  Completed-Overlay mit Kreis-Checkmark.
-
----
-
-### ✅ Phase 5.5 — Browse-Menü: Kategorien + Top Live-Streams
-
-Verifiziert 2026-04-08.
-
-#### Neue/geänderte Dateien:
-- `src/main/twitch/types.ts` — `HelixGame`, `GameInfo`, `game_id`+`language` in `HelixStream`
-- `src/main/twitch/helixClient.ts` — `getTopGames(limit, cursor?)`, `getTopStreams(opts?)`
-- `src/main/ipc/handlers.ts` — `twitch:get-top-games`, `twitch:get-top-streams`
-- `src/preload/index.ts` — `GameInfo`-Typ + neue API-Methoden
-- `src/renderer/src/types/t4sd.d.ts` — `GameInfo`, T4sdApi erweitert
-- `src/renderer/src/input/gamepad.ts` — Button 2 (X) → `'x'`, Button 3 (Y) → `'y'`
-- `src/renderer/src/screens/BrowseScreen.tsx` — Shelf (Top Live) + Kategorien-Grid
-- `src/renderer/src/screens/CategoryScreen.tsx` — neu: Streams-Grid pro Kategorie
-- `src/renderer/src/screens/AppShell.tsx` — `selectedCategory`-Routing
-
-#### Key-Mapping Browse + Category:
-- **Enter / A**: Stream → direkt Live starten · Kategorie → Drilldown
-- **X**: Stream-Karte → ChannelScreen öffnen (VOD-Shelf + Live-Button)
-- **Y**: Refresh
-- **Escape / B**: Category → zurück zu Browse · Browse → Sidebar
-
-#### Wichtige Implementierungsdetails:
-- `getTopGames()` macht 40 parallele `/streams?game_id=<id>&first=100` Calls für Zuschauerzahlen
-  (Top-100-Streams pro Kategorie summiert → ~85-95% Genauigkeit vs. Twitch-Website).
-- Pagination: `getTopGames()` gibt `{ games, cursor }` zurück. BrowseScreen lädt automatisch
-  nächste 40 Kategorien wenn letztes Grid-Element fokussiert wird.
-- `getTopStreams()` global mit `limit: 100` für den Shelf.
-- Zuschauerzahlen auf Kategorien zeigen `n.toLocaleString('de-DE')` Format.
-
----
-
-### ✅ Phase 5.6 — Einstellungen-Menü + Sprach-Badge/Flagge
-
-Verifiziert 2026-04-08.
-
-#### Neue Dateien:
-- `src/renderer/src/context/SettingsContext.tsx` — `SettingsProvider`, `useSettings()` Hook,
-  localStorage-Persistenz (`t4sd:settings`), Fallback auf Default bei korrupten Werten
-- `src/renderer/src/components/LanguageBadge.tsx` — rendert Badge/Flagge/Beides je nach Mode;
-  38 Sprachen gemappt (pragmatische Twitch-Dominanz-Zuordnung)
-- `src/renderer/src/screens/SettingsScreen.tsx` — 4 Optionen, gamepad-navigierbar
-
-#### Geänderte Dateien:
-- `src/main/twitch/types.ts` — `language` in `HelixStream` + `FollowedChannelInfo`
-- `src/main/twitch/helixClient.ts` — `language` in beiden Stream-Mappern
-- `src/preload/index.ts` + `t4sd.d.ts` — `language?: string` in `FollowedChannelInfo`
-- `src/renderer/src/components/Icons.tsx` — `SettingsIcon` (Zahnrad)
-- `src/renderer/src/components/Sidebar.tsx` — 4. Tab `'settings'`
-- `src/renderer/src/components/FocusableCard.tsx` — `<LanguageBadge>` unten-rechts im Thumb
-- `src/renderer/src/screens/BrowseScreen.tsx` — `<LanguageBadge>` in Shelf-Cards
-- `src/renderer/src/screens/AppShell.tsx` — `tab === 'settings'` → SettingsScreen
-- `src/renderer/src/main.tsx` — `<SettingsProvider>` um App
-
-#### Architektur-Entscheidungen:
-- Settings in `localStorage` (nicht SQLite) — reine UI-Präferenz, kein IPC nötig,
-  synchron lesbar (kein Flicker beim Start).
-- Default-Mode: `'language'` (Kürzel wie DE/EN) — funktioniert auf Windows Dev-Host sicher.
-  Flaggen-Emojis (Unicode Regional Indicators) werden erst auf Steam Deck (Linux/Noto Emoji)
-  korrekt gerendert — auf Windows Dev-Host ggf. Rechtecke statt Flaggen.
-- `StreamBadgeMode`: `'off' | 'language' | 'flag' | 'both'`
-- LanguageBadge Position: `bottom: 10px; right: 10px` im Thumbnail (gegenüber Viewer-Count
-  unten-links). Font-Size 15px (FocusableCard) / 14px (Browse-Shelf) > 13px Viewer-Count.
-- Unbekannte Sprachen / `'other'` → kein Badge.
-

-
-## Phase 6 — Flatpak-Packaging (in Arbeit, wartet auf WSL2 + Steam Deck)
-
-Ziel: App läuft auf dem Steam Deck als Flatpak.
-
-#### Neue Dateien (Phase 6):
-- `flatpak/tv.twitch4steamdeck.App.yml` — Flatpak-Manifest (mpv + streamlink als Module)
-- `flatpak/twitch4steamdeck.sh` — Launcher mit `zypak-wrapper` (Electron-Sandbox)
-- `flatpak/tv.twitch4steamdeck.App.desktop` — Desktop-Eintrag
-- `flatpak/build-flatpak.sh` — Build-Skript für WSL2 (prüft deps, füllt SHA256, baut)
-- `resources/icons/icon.svg` — App-Icon (Platzhalter, konvertiert zu PNG beim Build)
-
-#### Architektur-Entscheidungen:
-- **Pre-Build in WSL2:** `npm install` + `@electron/rebuild` + `npm run build` laufen
-  AUSSERHALB von flatpak-builder in WSL2. Das Manifest kopiert nur die Artefakte.
-  → Vermeidet npm-im-Flatpak-Sandbox-Probleme.
-- **Electron-Binary aus npm:** Das Electron-Binary kommt aus `node_modules/electron/dist/electron`
-  (npm install für Linux), NICHT aus dem BaseApp. BaseApp liefert nur Chrome-Runtime-Libs + zypak.
-- **zypak-wrapper:** Ersetzt Chrome-Setuid-Sandbox für Flatpak-Kompatibilität.
-- **mpv:** Aus Sources gebaut, libplacebo deaktiviert (entfernt Vulkan-Abhängigkeitskette),
-  ffmpeg/libass/libva kommen aus freedesktop SDK 24.08.
-- **streamlink:** Via pip install ins Flatpak gebaut. Für sauberen Offline-Build:
-  `flatpak-pip-generator` für Python-Dependencies verwenden (TODO beim echten Build).
-- **better-sqlite3:** Muss für Linux x64 rebuilt werden (Steam Deck = AMD Zen2 x86_64,
-  NICHT ARM64 — die alte ARM64-Notiz war falsch).
-- **IPC-Socket:** `os.tmpdir()` → `/tmp` — beide Prozesse (Electron-Main + mpv-Child)
-  teilen denselben Flatpak-Sandbox-Namespace. Kein Code-Fix nötig.
-- **VAAPI:** `--hwdec=vaapi` bereits implementiert für non-win32 in `streamlink.ts:73`.
-- **Flaggen-Emojis erst hier testbar** (Noto Color Emoji aus freedesktop Platform Runtime)
-
-#### Noch ausstehend (User):
-1. WSL2-Setup: `sudo apt install flatpak flatpak-builder librsvg2-bin`
-2. `bash flatpak/build-flatpak.sh` (in WSL2, aus `/mnt/c/Projekte/twitch4steamdeck`)
-3. Verifikation auf Steam Deck: Login, Live, VOD, Resume, Gamepad, Gaming Mode
-
----
-
-## Technische Baseline
-
-- Electron 33, electron-vite, TypeScript 5.5, React 18
-- better-sqlite3 12.x (native, rebuilt für Electron via `@electron/rebuild`)
-- streamlink 8.x unter `%LOCALAPPDATA%\Programs\Streamlink\bin\streamlink.exe`
-- mpv v0.41.0 unter `C:\Program Files\MPV Player\mpv.exe`
-- Dev-Host: **Windows**. Target: **Steam Deck (Linux / Flatpak)**
-
-### Wichtiges Projekt-Memo
-- Bei **allen Architekturänderungen** `plan.md` updaten.
-- Nach **jeder Subaufgabe** Checkbox in `todo.md` setzen und Update hier.
-- Dev-Host: **Windows**. Target: **Steam Deck (Linux / Flatpak)**.
-- **Nicht** mit Speculative Abstractions aufblähen.

-Fertige Flatpak-Bundles enthalten alles (inkl. mpv, Streamlink und Twitch-Anbindung) -- keine weitere Einrichtung noetig.
+Finished Flatpak bundles include everything (incl. Streamlink and Twitch integration) — no further setup required.
+
+---
+
+## Build yourself (developers)
+
+### Prerequisites
+
+- [Node.js](https://nodejs.org/) >= 20
+- npm
+- Windows: Streamlink installed at `%LOCALAPPDATA%\Programs\Streamlink\bin\streamlink.exe`
+- For Flatpak build: WSL2 (Ubuntu) with `flatpak`, `flatpak-builder`, `librsvg2-bin`
+
+### Setup
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/<user>/twitch4steamdeck.git
+   cd twitch4steamdeck
+   ```
+
+2. Register your own Twitch app at https://dev.twitch.tv/console/apps:
+   - **OAuth Redirect URLs:** `http://localhost`
+   - **Client Type:** Public
+
+3. Create `.env`:
+   ```bash
+   cp .env.example .env
+   ```
+   Enter the Client ID from step 2 into `.env`:
+   ```
+   MAIN_VITE_TWITCH_CLIENT_ID=your_client_id_here
+   ```
+
+   > The Client ID is embedded into the app at build time. End users installing a finished Flatpak do not need to register their own Twitch app.
+
+4. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+### Development
+
+```bash
+npm run dev
+```
+
+Starts Electron with Hot-Reload (electron-vite). Open DevTools with `Ctrl+Shift+I`.
+
+## Build
+
+### Desktop (AppImage)
+
+```bash
+npm run package
+```
+
+Creates a Linux AppImage under `dist/`.
+
+### Flatpak (Steam Deck)
+
+The Flatpak build must run in WSL2 on the Linux filesystem (not under `/mnt/`):
+
+```bash
+# Copy project to Linux filesystem
+cp -rp /mnt/c/Projekte/twitch4steamdeck ~/twitch4steamdeck
+cd ~/twitch4steamdeck
+
+# Run full build (incl. streamlink, Electron)
+bash flatpak/build-flatpak.sh
+```
+
+The script handles automatically:
+1. Install Flatpak runtimes (freedesktop SDK 24.08, Electron2 BaseApp)
+2. npm install + rebuild native modules (better-sqlite3 for Linux x64)
+3. electron-vite build
+4. Generate Streamlink Python deps
+5. Run flatpak-builder
+6. Create Flatpak bundle and transfer via SCP to Steam Deck
+
+## Gamepad Layout

+| B | Navigation | Back |
+| D-Pad / Left Stick | Navigation | Navigate |
+| LB / RB | Navigation | Switch tabs |
+| Xbox / Start | Navigation | Quit dialog |
+
+## Security
+
+- **Twitch tokens** are stored encrypted in the OS keystore (Electron `safeStorage`) and never end up in the build or repository
+- **Client ID** is a public identifier (Public App) and not a secret
+- `.env`, `out/`, `dist/` and `userData/` are excluded in `.gitignore`

-# Twitch4SteamDeck — Architekturplan
-
-> Spiegel von `C:\Users\andre\.claude\plans\smooth-shimmying-parasol.md`.
-> Fortschritt steht in `todo.md`, aktueller Stand in `CLAUDE_PROGRESS.md`.
-
-## Ziel
-
-Steam-Deck-App zur **werbefreien** Wiedergabe von Twitch-Livestreams und -VODs.
-Big-Screen-/10-Foot-UI, vollständig per Gamepad bedienbar. Lokaler VOD-Verlauf
-mit Resume. Verteilung als Flatpak.
-
-## Tech-Stack (entschieden)
-
-| Bereich | Wahl |
-|---|---|
-| Sprache/Runtime | TypeScript + Electron (Main + Renderer) |
-| UI | React + CSS, Spatial-Navigation für Gamepad |
-| Wiedergabe | externer **mpv**-Prozess via JSON-IPC-Socket |
-| Stream-Quelle / Ad-Bypass | **Streamlink** (Subprozess) + `--twitch-disable-ads`, optional TTV.LOL |
-| Twitch-Auth | **OAuth 2.0 Device Code Flow** |
-| Twitch-Daten | Helix-API (`api.twitch.tv/helix`) |
-| Token-Storage | Electron `safeStorage` → `userData/twitch-tokens.bin` |
-| Lokale Persistenz | SQLite via `better-sqlite3` (VOD-Verlauf, Settings) |
-| Packaging | `electron-builder` → Flatpak |
-
-## MVP-Scope
-
-1. Twitch-Login via Device Code Flow
-2. Followed Channels (Liste, Live-Indicator)
-3. Live-Stream-Wiedergabe werbefrei (Streamlink → mpv)
-4. VOD-Browsing pro Kanal
-5. VOD-Wiedergabe werbefrei
-6. Lokaler VOD-Verlauf + Resume
-7. Browse: Top Live-Streams + Kategorien (mit Zuschauerzahlen, Infinite Scroll)
-8. Einstellungen: Sprach-Badge / Flagge auf Thumbnails
-
-**Bewusst nicht im MVP:** Chat/Emotes, Suche (Text-Input), PiP, Themes.
-

-└─────────────────────────────────────────────────┘
-```
-
-Wiedergabe läuft **außerhalb** Electron in einem mpv-Vollbildfenster.
-Electron startet/stoppt mpv, sendet Befehle, lauscht auf `time-pos` für Verlaufsspeicherung.
-
-## Architektur-Abweichungen (aktuell)
-
-Zusätzlich zu den ursprünglichen Abweichungen:
-- **Browse-Screen** (`BrowseScreen.tsx`) ist kein Platzhalter mehr, sondern
-  ein vollständiger Screen mit Shelf (Top Live) + Kategorien-Grid.
-- **CategoryScreen** (`CategoryScreen.tsx`) neu: Drilldown aus Browse in
-  Streams einer Kategorie. Key-Mapping: Enter=Live, X=ChannelScreen, B=zurück.
-- **SettingsContext** (`context/SettingsContext.tsx`): globaler React-Context
-  mit localStorage-Persistenz für UI-Präferenzen. Kein IPC nötig.
-- **LanguageBadge** (`components/LanguageBadge.tsx`): rendert Sprachkürzel/Flagge
-  auf Thumbnails. Flaggen = Unicode-Emoji, auf Steam Deck (Noto Emoji) korrekt.
-- **Gamepad Button 2 (X) + 3 (Y)** jetzt gemappt: `'x'` / `'y'`.

-
-**Architektur-Abweichungen vom Original-Plan (bewusst):**
-- `HomeScreen.tsx` wurde durch `FollowingScreen.tsx` ersetzt und in ein `AppShell.tsx`-Layout
-  mit linker `Sidebar.tsx` (3 Tabs: Du folgst / Durchsuchen / Mein Account) eingebettet.
-- Spatial-Navigation ist eine **eigene Implementierung** (Region-basiert: `sidebar` ↔ `main`),
-  kein `@noriginmedia/norigin-spatial-navigation`. Grund: einfacher, keine externe Dependency,
-  volle Kontrolle über das Region-Switch-Verhalten.
-- `FocusableCard` nutzt **Block-Layout** (nicht Flex), weil Flex im Zusammenspiel mit
-  `aspect-ratio` und Grid-Zellen Schrumpf-Artefakte hatte.
-
-## Kernkomponenten — Spezifikation
-
-### Auth (✅ implementiert)
-- Endpoint `POST https://id.twitch.tv/oauth2/device` mit `client_id` + `scopes` (space-sep).
-- Anzeige `user_code` + `verification_uri` + QR.
-- Polling `POST https://id.twitch.tv/oauth2/token` mit
-  `grant_type=urn:ietf:params:oauth:grant-type:device_code`.
-- Refresh-Token via Electron `safeStorage`.
-- Auto-Refresh wenn Helix 401.
-- Client-ID via `MAIN_VITE_TWITCH_CLIENT_ID` (`.env` im Projektroot, electron-vite lädt sie).
-- Scope MVP: `user:read:follows`.
-
-### Helix-Client (✅ implementiert)
-Implementierte Endpoints (in `src/main/twitch/helixClient.ts`):
-- `GET /users` (eigener User → `cachedUserId`)
-- `GET /users?id=…` (batched, für Avatare der Followed-Kanäle)
-- `GET /channels/followed?user_id=…` (paginiert via `after`, safety-cap 500)
-- `GET /streams?user_id=…` (batched, max 100 IDs/Call)
-- `GET /videos?user_id=…&type=archive` — `getVideos()` ✅
-- `GET /games/top?first=40&after=<cursor>` — `getTopGames(limit, cursor?)` ✅ Phase 5.5
-  - Gibt `{ games: GameInfo[], cursor?: string }` zurück (Pagination)
-  - Macht 40 parallele `/streams?game_id=<id>&first=100` Calls für Zuschauerzahlen
-- `GET /streams` (global `limit:100` + optional `game_id`) — `getTopStreams(opts?)` ✅ Phase 5.5
-  - Reichert mit Avataren an (`getProfileImages`, batched)
-  - Gibt `FollowedChannelInfo[]` zurück (inkl. `gameId`, `language`)
-
-Header: `Client-Id: <id>`, `Authorization: Bearer <access_token>`.
-`getFollowedWithLiveStatus()` merged Followed + Live + Avatare zu `FollowedChannelInfo[]` und
-sortiert live-zuerst, dann alphabetisch.
-
-### Streamlink + mpv (✅ Phase 3 + 4)
-
-**Zwei unterschiedliche Spawn-Strategien (implementiert):**
-
-**Live-Streams** (`spawnStreamlink`):
-```
-streamlink --player <mpv-bin> --player-args "--fullscreen" twitch.tv/<channel> best
-```
-- streamlink spawnt mpv als Kind-Prozess, kein IPC
-- `--twitch-disable-ads` wurde von streamlink deaktiviert (deprecated) — kein Ad-Bypass
-- `--twitch-api-header=Authorization=OAuth` wird **nicht** übergeben: Twitch lehnt
-  Device-Code-Flow-Token für streamlinks interne GQL-API ab
-
-**VODs** (`getStreamUrl` + `spawnMpv`):
-```
-# Schritt 1: HLS-URL abrufen
-streamlink --stream-url https://www.twitch.tv/videos/<id> best
-# → gibt z.B. https://…/playlist.m3u8 zurück
-
-# Schritt 2: mpv direkt mit HLS-URL starten
-mpv <hls-url> --input-ipc-server=<ipcPath> --fullscreen --hwdec=<auto|vaapi> --start=<resumePos>
-```
-- mpv wird direkt gespawnt (nicht via streamlink) → HLS-URL ist seekable → Seeking/Fortschrittsbalken funktioniert
-- IPC funktioniert zuverlässig (direkter mpv-Prozess, kein Pfad-Escaping durch streamlink)
-- `--hwdec=auto` auf Windows, `--hwdec=vaapi` auf Linux/Steam Deck
-
-**IPC-Pfade:**
-- Windows: Named Pipe `\\.\pipe\twitch4sd-mpv`
-- Linux/Flatpak: Unix Socket `/tmp/twitch4sd-mpv.sock`
-
-**mpvController** (`src/main/playback/mpvController.ts`):
-- `connect(retries, delayMs)` — verbindet nach Spawn
-- `observeTimePos(cb)` — registriert `observe_property 1 time-pos`, parst JSON-Lines
-- `quit()` — sendet `{"command":["quit"]}` via IPC
-- Wird bei Live-Streams instanziiert aber nie verbunden (harmlos)
-
-**IPC zwischen Renderer und Main:**
-- `playback:start-live` → `(channelLogin, quality?)` → `PlaybackService.startLive()`
-- `playback:start-vod` → `(vodId, channelLogin, title, durationSeconds)` → `PlaybackService.startVod()`
-- `playback:stop` → `PlaybackService.stop()`
-- `playback:event` (main → renderer) → `{kind: 'started'|'stopped'|'error', message?}`
-
-### VOD-History-DB (✅ Phase 5)
-```sql
-CREATE TABLE vod_history (
-  vod_id                   TEXT PRIMARY KEY,
-  channel_login            TEXT NOT NULL,
-  title                    TEXT,
-  duration_seconds         INTEGER,
-  resume_position_seconds  INTEGER NOT NULL DEFAULT 0,
-  watched_at               INTEGER NOT NULL,
-  completed                INTEGER NOT NULL DEFAULT 0
-);
-CREATE INDEX IF NOT EXISTS idx_history_watched ON vod_history(watched_at DESC);
-```
-- DB-Pfad: `app.getPath('userData')/history.db`, WAL-Modus
-- Complete-Threshold: `resume_position / duration > 0.95`
-- `„Continue Watching"-Reihe` bewusst weggelassen (nicht benötigt)
-- IPC: `history:get-progress` → `(vodIds: string[]) → Record<vodId, VodProgress>`
-- VOD-Karte zeigt: Fortschrittsbalken, `0:16 von 6:22`, `Vor X Min.`, Completed-Overlay
-
-### Big-Screen-UI / Gamepad
-- Spatial-Navigation-Lib oder eigene Mini-Implementierung.
-- Fokus-Ring deutlich sichtbar.
-- Schrift: min. 22px Body, 36px+ Headlines.
-- Mapping: D-Pad/Stick = Navigation, A = Aktivieren, B = Zurück, Y = Refresh, Start = Menü, L1/R1 = Tab.

-### Settings (✅ Phase 5.6)
-
-- Persistenz: `localStorage`, Key `t4sd:settings`, synchron lesbar (kein Flicker)
-- Shape: `{ streamBadgeMode: 'off' | 'language' | 'flag' | 'both' }`
-- Default: `'language'`
-- React Context: `SettingsProvider` um `<App>`, `useSettings()` Hook
-- Flaggen: Unicode Regional Indicator Emojis — auf Steam Deck (Noto Color Emoji) korrekt,
-  auf Windows Dev-Host ggf. Rechtecke
-- `LanguageBadge` rendert in Thumbnails: unten-rechts (gegenüber Viewer-Count unten-links)
-- 38 Sprachen gemappt (pragmatische Twitch-Dominanz: `pt→🇧🇷`, `en→🇺🇸`, `zh→🇹🇼`)
-
-### Flatpak (✅ Phase 6 — Dateien erstellt, Verifikation auf Steam Deck ausstehend)
-- Runtime: `org.freedesktop.Platform//24.08`, `org.electronjs.Electron2.BaseApp//24.08`
-- Module: `mpv` (aus Sources, libplacebo disabled), `streamlink` (pip), App-Bundle
-- Permissions: `--share=network`, `--share=ipc`, `--socket=wayland`, `--socket=fallback-x11`,
-  `--socket=pulseaudio`, `--device=dri`
-- Pre-Build-Strategie: `npm install` + `@electron/rebuild` + `npm run build` in WSL2,
-  dann Artefakte per `type:dir` Source ins Flatpak kopieren
-- Launcher: `zypak-wrapper node_modules/electron/dist/electron out/main/index.js`
-- Build-Skript: `flatpak/build-flatpak.sh` (WSL2, prüft deps, füllt SHA256, baut)
-
-## Verifikation
-
-End-to-End auf Steam Deck oder Linux-Box:
-1. Build: `npm install && npm run build && flatpak-builder --user --install build-dir flatpak/…yml`
-2. Login-Flow mit Device-Code + Smartphone
-3. Live-Stream 5+ Min ohne Werbe-Unterbrechung (Streamlink-Debug-Logs gegenchecken)
-4. VOD ansehen, mpv beenden, neu starten → springt an gespeicherte Position
-5. Komplette Bedienung nur mit Steam-Deck-Controller
-6. Im Gaming Mode als Non-Steam-Game starten und alles wiederholen
-
-## Offene Punkte (Post-MVP)
-- Eigene `client_id` im Build vor Release.
-- Chat / Emotes (BTTV/FFZ/7TV).
-- Suche (Text-Input am Gamepad — eigenes UX-Problem).
-- README + ToS-Disclaimer (Twitch-Werbeumgehung kann gegen ToS verstoßen).
-- Weitere Einstellungen (Qualität, Theme, ...) — Infrastruktur mit SettingsContext bereit.

-# Twitch4SteamDeck — TODO
-
-> Checkboxen-Tracker. Nach jedem erledigten Punkt sofort abhaken und kurzes
-> Update in `CLAUDE_PROGRESS.md` ergänzen.
-
-## Phase 0 — Projekt-Skelett
-- [x] `package.json`, tsconfig (root/node/web)
-- [x] `electron.vite.config.ts`, `electron-builder.yml`, `.gitignore`
-- [x] Main-Stub mit BrowserWindow
-- [x] Preload-Stub mit `contextBridge`
-- [x] Renderer (React + Big-Screen-Baseline-CSS)
-- [x] Smoke-Test: `npm install && npm run dev` zeigt Fenster
-
-## Phase 1 — Twitch OAuth Device Code Flow
-- [x] `deviceCodeFlow.ts` (request + polling + refresh)
-- [x] `tokenStore.ts` (safeStorage-Persistenz)
-- [x] `authService.ts` (Lifecycle + EventEmitter)
-- [x] IPC-Handler + Preload-Bridge
-- [x] `LoginScreen.tsx` (QR + Code + Countdown)
-- [x] `App.tsx` Routing nach Auth-Status
-- [x] `.env.example`
-- [x] **End-to-End-Verifikation durch User** (Login mit echter Twitch-App durchführen)
-- [x] Token-Persistenz prüfen: App-Neustart → bleibt eingeloggt
-- [ ] Logout testen: `userData/twitch-tokens.bin` wird gelöscht (später)
-
-## Phase 2 — Twitch Helix-Client + Followed-Channels-Home-Screen
-- [x] `src/main/twitch/types.ts` (Helix-Response-Typen)
-- [x] `src/main/twitch/helixClient.ts` (fetch-Wrapper, Auth-Header, Client-ID-Header, Paginierung)
-- [x] Helix-Endpoints implementieren:
-  - [x] `GET /users` (eigener User → user_id cachen)
-  - [x] `GET /channels/followed?user_id=…` (paginiert)
-  - [x] `GET /streams?user_id=…` (batched, max 100 IDs pro Call)
-- [x] IPC: `twitch:get-followed` registrieren (merged live-Status + Avatar)
-- [x] Preload-API erweitern: `window.t4sd.twitch.getFollowed`
-- [x] `FollowingScreen.tsx` — Karten-Grid mit Live-Indicator, Vorschaubild, Titel, Zuschauerzahl
-- [x] Spatial-Navigation: eigene Implementierung (Arrow-Keys + Region-Switch Sidebar ↔ Main)
-- [x] Gamepad-Service: `src/renderer/src/input/gamepad.ts` (Gamepad-API → Keyboard-Events)
-- [x] `FocusableCard.tsx` — Block-Layout, Avatar + Name + Titel + Spiel + Viewer-Badge
-- [x] `AppShell.tsx` + `Sidebar.tsx` — Layout mit linker Navigation (Du folgst / Durchsuchen / Mein Account)
-- [x] `Icons.tsx` — inline SVG-Icons (Heart, Compass, User)
-- [x] `BrowseScreen.tsx` + `AccountScreen.tsx` — Platzhalter-Screens mit Logout
-- [x] **End-to-End-Verifikation durch User** (2026-04-07: Karten + Tastatur-Nav bestätigt)
-
-## Phase 3 — Streamlink + mpv (Live-Wiedergabe)
-
-### Vorab (Dev-Setup, Windows)
-- [x] **User:** `mpv` installieren — `winget install shinchiro.mpv`, via `setx` zum PATH
-- [x] **User:** `streamlink` installieren — `winget install streamlink` (8.2.1)
-- [x] **User:** Baseline-Test erfolgreich:
-      `streamlink --twitch-disable-ads twitch.tv/streamerhouse best --player mpv`
-
-### Backend (Main-Prozess)
-- [x] `src/main/playback/types.ts`
-- [x] `src/main/playback/streamlink.ts` — `resolveStreamlinkBin()` (Win32-Pfad-Auflösung),
-      `spawnStreamlink()` mit `--player mpv --player-args "..."` (Variante 2)
-- [x] `src/main/playback/mpvController.ts` — Named Pipe (Win32) / Unix Socket (Linux),
-      connect mit Retry, `quit()`, `disconnect()`
-- [x] `src/main/playback/playbackService.ts`
-- [x] IPC-Kanäle: `playback:start-live`, `playback:stop`, `playback:event`
-
-### Renderer (UI)
-- [x] Preload + `t4sd.d.ts` erweitern: `window.t4sd.playback.{startLive, stop, onEvent}`
-- [x] `src/renderer/src/screens/ChannelScreen.tsx` (Hero + Live-Button + Zustandsanzeige)
-- [x] Routing in `AppShell.tsx`: `selectedChannel`-State → `ChannelScreen`
-- [x] `FocusableCard.onSelect` → setzt `selectedChannel` via `onSelectChannel`-Prop
-- [x] Spatial-Nav: Escape/B im ChannelScreen → Stop oder Zurück
-
-### Verifikation
-- [x] Stream startet: mpv-Fenster öffnet sich, Stream spielt ab (2026-04-08)
-      _(Fix: --twitch-api-header entfernt, resolveMpvBin() ergänzt)_
-- [x] **User:** Stop-Verhalten: mpv-Fenster schließt sich, keine Zombie-Prozesse (2026-04-08)
-- [x] **User:** Logout → Login → Stream starten funktioniert ohne App-Neustart (2026-04-08)
-      ⚠️ `--twitch-disable-ads` ist von streamlink deaktiviert — Werbung wird ggf. abgespielt (Post-MVP)
-
-## Phase 4 — VOD-Browsing + -Wiedergabe
-- [x] Helix `GET /videos?user_id=…&type=archive` → `getVideos()` in helixClient
-- [x] VOD-Shelf im ChannelScreen (horizontal, obere Hälfte fix)
-- [x] `playback:start-vod` IPC-Kanal + `PlaybackService.startVod()`
-- [x] mpv `--start=<seconds>` beim Spawn (Parameter vorbereitet für Phase 5)
-- [x] **User:** VOD-Wiedergabe + Stop-Verhalten verifiziert (2026-04-08)
-
-## Phase 5 — Lokaler VOD-Verlauf (Resume)
-- [x] SQLite-Setup: `src/main/store/db.ts` (better-sqlite3, Migration)
-- [x] `historyRepo.ts` mit `vod_history`-Tabelle
-- [x] mpv `time-pos`-Observer schreibt alle ~5s in DB
-- [x] Auto-Resume: beim VOD-Start Position aus DB lesen → `--start=<s>`
-- [x] Auto-Complete bei >95% Wiedergabefortschritt
-- [x] Resume-Indikator auf VOD-Karte (Fortschrittsbalken + „0:16 von 6:22" + „Vor X Min.")
-- [x] Completed-Indikator (dunkles Overlay + Checkmark)
-- [x] **User:** Verifiziert (2026-04-08)
-- ~~„Continue Watching"-Reihe~~ — entfällt (nicht benötigt)
-
-## Phase 5.5 — Browse-Menü: Kategorien + Top Live-Streams
-
-- [x] `HelixGame`, `GameInfo` Typen in `types.ts`
-- [x] `helixClient.ts`: `getTopGames()` + `getTopStreams(gameId?)`
-- [x] IPC: `twitch:get-top-games`, `twitch:get-top-streams`
-- [x] Preload + `t4sd.d.ts`: Typen + API-Methoden
-- [x] `gamepad.ts`: Button 2 (X) → `'x'`, Button 3 (Y) → `'y'`
-- [x] `BrowseScreen.tsx`: Shelf (Top Live) + Grid (Kategorien), Key-Mapping
-- [x] `CategoryScreen.tsx`: Streams-Grid pro Game
-- [x] `AppShell.tsx`: `selectedCategory`-Routing
-- [x] `global.css`: Browse/Game-Card-Styles
-- [x] **User:** End-to-End-Verifikation (Browse laden, Live starten, Kategorie-Drilldown)
-
-## Phase 5.6 — Einstellungen + Sprach-Badge/Flagge
-
-- [x] `language` in `HelixStream` + `FollowedChannelInfo` (types.ts, preload, t4sd.d.ts)
-- [x] `helixClient.ts`: `language` in `getTopStreams` + `getFollowedWithLiveStatus`
-- [x] `SettingsContext.tsx`: Provider + `useSettings()` + localStorage-Persistenz
-- [x] `Icons.tsx`: `SettingsIcon` (Zahnrad)
-- [x] `Sidebar.tsx`: 4. Tab „Einstellungen"
-- [x] `LanguageBadge.tsx`: Badge/Flag/Both Rendering + 38-Sprachen-Map
