## Fullscreen-Player (now_playing_screen.dart) - Glow-Farbe folgt MeloTheme.akzentNotifier (Per-User-Akzent) statt fixem Rot; Listener rebuildet bei Akzentwechsel - Dynamische Glow-Pulsation: AnimationController (Bordmittel) pulsiert blurRadius 50–70 / spreadRadius 6–12 nur bei Wiedergabe, stillstehend bei Pause - Blur-Hintergrund crossfaded beim Songwechsel (AnimatedSwitcher 600ms, layoutBuilder mit StackFit.expand, ValueKey je Song) - existsSync aus dem Build-Pfad entfernt: async _ladeCoverStatus mit try/catch, Guard gegen stale Song-Wechsel
