Playlist browser:
- GET /api/playlist returns all track titles via ReadProcessMemory
- WS command {cmd:jump, index:N} jumps to track (0-based)
- Full-screen overlay with scrollable list
- Current track highlighted, auto-scrolls into view on open
- Live highlight update when track changes while panel is open

PWA:
- manifest.json with standalone display + theme colour
- sw.js: cache-first service worker for shell files
- icon.svg: music-note icon on dark background
- Apple/Android meta tags for Add to Homescreen

Canvas / viz:
- Idle animation when Winamp stopped/paused: slow sine-wave breathing
  across bars at low amplitude, dim colours — canvas is never dead-black
- 'PLAY' label overlay when stopped, 'NO SIGNAL' when WS disconnected
- hasSignal check: viz data must be < 1.5s old AND Winamp playing
- DPR resize uses Math.round() to avoid sub-pixel canvas size mismatch
- Peak indicators fade quickly in idle mode

winamp.go:
- GetPosition: clamp 0xFFFFFFFF sentinel at source (> 0xF0000000 → 0)
  instead of in server.go; also removed redundant clamp from statusMsg
- GetTitle: use strings.LastIndex/Index instead of hand-rolled helpers
  Returns empty string when window title is just 'Winamp' (stopped/empty)
  Playlist prefix strip is now bounded (dot <= 4) so track titles with
  '. ' in them are not accidentally trimmed
