Removed the master effects section from AudioEditor footer:
- Simplified footer to only show transport controls
- Removed master channel strip area
- Removed border separator between sections
Added note to PLAN.md:
- 🔲 Master channel effects (TODO)
- Will implement master effect chain UI later
- Similar to per-track effects but for final mix
- Documented in Phase 7 multi-track features section
This cleans up the UI for now - we'll add master effects
with a proper device rack UI later, similar to how per-track
effects work (collapsible section with horizontal device cards).

Implemented MutationObserver to detect theme changes:
- Added themeKey state that increments on theme change
- MutationObserver watches document.documentElement for class changes
- Detects when "dark" class is toggled
- Added themeKey to waveform effect dependencies
- Canvas automatically redraws with new theme colors
How it works:
1. Observer listens for class attribute changes on <html>
2. When dark mode is toggled, themeKey increments
3. useEffect dependency triggers canvas redraw
4. getComputedStyle reads fresh --color-waveform-bg value
5. Waveform renders with correct theme background
Benefits:
- Seamless theme transitions
- Waveform colors always match current theme
- No manual refresh needed
- Automatic cleanup on unmount
Now switching between light/dark themes instantly updates
all waveform backgrounds with the correct theme colors!

Visual improvements:
- Effects section background now matches waveform (slate-900/50)
- More subtle border (border-border/50)
- Compact header (py-1.5 instead of py-2)
- Expanded area has darker background (slate-900/30) for depth
Collapsed state improvements:
- When collapsed, shows mini effect chips in the header
- Each chip shows effect name with visual state:
- Enabled: primary color with border (blue/accent)
- Disabled: muted with border
- Chips are scrollable horizontally if many effects
- Falls back to "Devices (count)" when no effects
Better integration:
- Background colors tie to waveform area
- Subtle hover effect on header (accent/30)
- Visual hierarchy: waveform -> effects blend together
- No more "abandoned" feeling - feels like part of the track

- Removed "Devices" button from control panel
- Effects section now always present below each track
- Collapsible via chevron in the effects header itself
- Click header to expand/collapse the device rack
- "+" button in header to add effects (with stopPropagation)
- Each track has independent collapse state
- Hover effect on header for better UX
This matches the typical DAW layout where each track has its own
device section that can be individually collapsed/expanded.

Major UX improvement inspired by Ableton Live's device view:
- Effects section now appears below the waveform in the track lane
- Toggle button in control panel shows/hides the effects area
- Gives much more horizontal space for device rack
- Effects section spans full width of track (control panel + waveform)
- Clean separation between track controls and effects
- Header with device count, add button, and close button
Layout changes:
- Track structure changed from horizontal to vertical flex
- Top row contains control panel + waveform (fixed height)
- Bottom section contains collapsible effects area (when shown)
- Effects hidden by default, toggled via "Devices" button
- When collapsed, track doesn't show effects section
This provides a cleaner workflow where users can focus on mixing
when effects are hidden, then expand to full device view when needed.

Created a beautiful effect browser dialog inspired by Ableton Live:
**EffectBrowser Component:**
- Modal dialog with search functionality
- Effects organized by category:
- Dynamics (Compressor, Limiter, Gate)
- Filters (Lowpass, Highpass, Bandpass, etc.)
- Time-Based (Delay, Reverb, Chorus, Flanger, Phaser)
- Distortion (Distortion, Bitcrusher)
- Pitch & Time (Pitch Shifter, Time Stretch)
- Utility (Normalize, Fade In/Out, Reverse)
- Grid layout with hover effects
- Real-time search filtering
- Click effect to add to track
**Integration:**
- "+" button in track strip opens EffectBrowser dialog
- Selecting an effect adds it to the track's effect chain
- Effects appear immediately in the Devices section
- Full enable/disable and remove functionality
**UX Flow:**
1. Click "+" in track Devices section
2. Browse or search for effect
3. Click effect to add it
4. Effect appears in Devices list
5. Toggle on/off with ●/○
6. Remove with × button
Effects are now fully manageable in the UI! Next: Apply them to audio.

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)
