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.

- When expanded, devices show parameter details
- Replaced vertical effect list with horizontal scrolling rack
- Effects display in 192px wide cards with visual feedback

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.
