- Integrated all R/S/A/E buttons into TrackControls component
- Removed duplicate button sections from Track component
- Updated CircularKnob pan visualization to show no arc at center position
- Arc now extends from center to value for directional indication
- Moved MasterControls to dedicated right sidebar
- Removed master controls from PlaybackControls footer
- Optimized TrackControls spacing (gap-1.5, smaller buttons)
- Cleaner separation between transport and master control sections

Unified design language across all tracks and master section:
- Created TrackFader component: vertical fader with horizontal meter bars
- Created TrackControls: integrated pan + fader + mute in compact layout
- Created MasterFader: similar design but larger for master output
- Created MasterControls: master version with pan + fader + mute
- Updated Track component to use new TrackControls
- Updated PlaybackControls to use new MasterControls
- Removed old VerticalFader and separate meter components
New features:
- Horizontal peak/RMS meter bars behind fader (top=peak, bottom=RMS)
- Color-coded meters (green/yellow/red based on dB levels)
- dB scale labels and numeric readouts
- Integrated mute button in controls
- Consistent circular pan knobs
- Professional DAW-style channel strip appearance
- Master section includes clip indicator
Visual improvements:
- Unified design across all tracks and master
- Compact vertical layout saves space
- Real-time level monitoring integrated with volume control
- Smooth animations and transitions

Completed the integration of recording functionality into the AudioEditor:
Recording Controls:
- Added global record button to PlaybackControls component
- Implemented track arming system (arm track before recording)
- Added visual feedback with pulsing red animations during recording
- Connected recording state from useRecording hook to UI
AudioEditor Integration:
- Added handleToggleRecordEnable for per-track record arming
- Added handleStartRecording with permission checks and toast notifications
- Added handleStopRecording to save recorded audio to track buffer
- Connected recording input level monitoring to track meters
TrackList Integration:
- Pass recording props (onToggleRecordEnable, recordingTrackId, recordingLevel)
- Individual tracks show input level meters when armed or recording
- Visual indicators for armed and actively recording tracks
This completes Phase 8 (Recording) implementation with:
✅ MediaRecorder API integration
✅ Input level monitoring with RMS calculation
✅ Per-track record arming
✅ Global record button
✅ Real-time visual feedback
✅ Permission handling
✅ Error handling with user notifications

Complete rewrite of seeking logic to support both scrubbing and
click-to-play functionality with proper state management.
Changes:
1. Added autoPlay parameter to seek() methods across the stack
2. Waveform behavior:
- Click and drag → scrubs WITHOUT auto-play during drag
- Mouse up after drag → auto-plays from release position
- This allows smooth scrubbing while dragging
3. Timeline slider behavior:
- onChange → seeks WITHOUT auto-play (smooth dragging)
- onMouseUp/onTouchEnd → auto-plays from final position
4. Transport button state now correctly syncs with playback state
Technical implementation:
- player.seek(time, autoPlay) - autoPlay defaults to false
- If autoPlay=true OR was already playing → continues playback
- If autoPlay=false AND wasn't playing → just seeks (isPaused=true)
- useAudioPlayer.seek() now reads actual player state after seeking
User experience:
✓ Click on waveform → music plays from that position
✓ Drag on waveform → scrubs smoothly, plays on release
✓ Drag timeline slider → scrubs smoothly, plays on release
✓ Transport buttons show correct state (Play/Pause)
