 **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.
 
+### Qualitätswahl während Wiedergabe
+- **Qualitätswechsel = streamlink-Neustart**: streamlink liefert Single-Bitrate-HLS → hls.js-Level-Switch nicht nutzbar. Wechsel: `videoRef.stop()` → `startLive/startVod(quality)` → neuer `hls-url` Event.
+- **VOD mit Resume**: `getCurrentTime()` vor Stop → als `startSeconds` an neues `startVod()`.
+- **Qualitätsliste**: asynchron nach Stream-Start via `playback:get-qualities` IPC → `streamlink --json <url>` → `Object.keys(json.streams)`, sortiert: `['best', '1080p60', '720p60', '480p', '360p', '160p', 'audio_only', 'worst']`
+- **Session-only**: kein Persistieren in Settings/localStorage.
+- **Panel-State im Parent**: `qualityPanelOpen`, `qualityFocusedIndex` in ChannelScreen/AppShell — PlaybackOverlay bekommt Props + Callbacks.
+- **Key-Handler Priorität**: `qualityPanelOpen`-Block wird VOR allen anderen Keys geprüft und gibt `return` — verhindert Seek/Pause-Konflikte während das Panel offen ist.
+- **X-Taste** öffnet Quality-Panel (Gamepad Button X → `x`-KeyboardEvent).

 ### 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).
+Wenn der User während der Wiedergabe das Kapitel-Panel öffnet (Y-Taste), läuft das Video **weiter** (nicht pausiert). `PlaybackOverlay` wird per conditional render (`!chapterPanelVod`) ausgeblendet, sodass das Kapitel-Panel sauber über dem Video erscheint. Nach Kapitelwahl: `seekTo(chapter.positionSeconds)` — kein `play()` nötig, da Video bereits läuft. Nach Schließen ohne Auswahl: Panel weg, Video läuft unverändert weiter. Bei leerer Kapitelliste: X-Taste seeked zu `0` (Videoanfang).
