+### Audio Player
+
+A site-wide floating audio player for transcription recordings (and future music library). Built with framer-motion for animations.
+
+- **Desktop**: Centered floating bar (max-width 680px) with cover image, track info, transport controls (prev/play/next), volume slider, source link, close button
+- **Mobile**: Auto-minimizes to a floating pill (cover image with circular progress ring and audio wave animation) after 8 seconds of inactivity. Tap to expand. Full player shows two rows: track info row + centered transport controls
+- **Z-index**: `z-40` — below text selection toolbar (z-80), drawers (z-90), modals (z-100)
+- **Hidden when selection toolbar is active** on mobile to avoid overlap
+- **Forced dark surface** (`bg-[#1c1c1e]`) for accessibility contrast regardless of theme
+- **Keyboard shortcuts**: Space (play/pause), ←/→ (seek ±10s), ↑/↓ (volume), M (mute), Esc (close)
+- **Progress seeker**: 8px tall bar at top of player, click/drag to seek
+- **Volume**: Persisted to localStorage. Mobile relies on hardware volume buttons
+- **framer-motion**: Spring animations for enter/exit, AnimatePresence for minimize/expand transitions, motion.div for audio wave bars
