- Track container now has fixed height (240px default or track.height)
- Waveform uses flex-1 to take remaining space
- Automation and effects bars use flex-shrink-0 for fixed height
- When bars expand, waveform shrinks instead of container growing
- Matches DAW behavior where track height stays constant

Fixed issues:
1. Made automation bar collapsible with chevron indicator
2. Removed border-t from automation lane container (no gap to effects)
3. Restored lane.visible filter so AutomationLane properly renders with controls
The AutomationLane component has all the rich editing UI:
- Click canvas to add automation points
- Drag points to move them
- Double-click to delete points
- Keyboard delete (Del/Backspace) for selected points
- Visual feedback with selected state
All controls are intact and functional when automation bar is expanded.

Changes:
- TrackControls.tsx: Removed entire Row 2 (A/E buttons section)
- TrackList.tsx: Removed click handler and chevron from automation header
- TrackList.tsx: Automation lane always visible (no conditional rendering)
- TrackList.tsx: Added border-b to effects bar container

Major improvements to automation and effects bars:
- Both bars now positioned at bottom of waveform (not top)
- Bars are always visible when track is expanded (no show/hide buttons)
- Effects bar at absolute bottom
- Automation bar above effects, dynamically positioned based on effects state
- Removed inner container from effects - direct rendering with EffectDevice
- Removed close buttons (X icons) - bars are permanent
- Effects render directly with gap-3 padding, no TrackExtensions wrapper
- Automation controls preserved (AutomationLane unchanged)
This creates a cleaner, always-accessible interface where users can quickly
expand/collapse automation or effects without toggling visibility.

Changes automation and effects from card-based overlays to integrated bars:
- Automation bar positioned at absolute top with no margins/padding
- Effects bar positioned below automation or at top if automation hidden
- Both bars use bg-card/90 backdrop-blur-sm for subtle transparency
- Collapsible with ChevronDown/ChevronRight indicators
- Close button (X icon) on each bar
- Effects bar dynamically positions based on automation state
- Added effectsExpanded property to Track type
- Removed card container styling for cleaner integration
The bars now sit directly on the waveform as requested, making them feel
more integrated into the track view rather than floating overlays.

Changes to automation and effects overlays:
- Reduced backdrop opacity from bg-black/60 to bg-black/30 (less dark)
- Added header to automation overlay with parameter name display
- Added close button to automation overlay (ChevronDown icon)
- Wrapped automation lane in rounded card with border and shadow
- Both overlays now have consistent visual styling
- Added ChevronDown import to TrackList
This makes the overlays less obtrusive and adds proper controls for closing
the automation view, matching the effects overlay pattern.

Automation lanes and effects now render as overlays on top of the waveform
instead of below the track, solving both visibility and layout proportion issues.
Changes:
- Wrapped Track waveforms in relative container for overlay positioning
- Automation lanes render with bg-black/60 backdrop-blur overlay
- Effects render with TrackExtensions in overlay mode (asOverlay prop)
- Added overlay-specific rendering with close button and better empty state
- Both overlays use absolute positioning with z-10 for proper stacking
- Eliminated height mismatch between controls and waveform areas
This approach provides better visual integration and eliminates the need
to match heights between the two-column layout.

Fixed multiple issues with the track layout system:
1. Effect cards now expandable/collapsible
- Added onToggleExpanded callback to EffectDevice
- Effect expansion state is properly toggled and persisted
2. Removed left column spacers causing misalignment
- Removed automation lane spacer (h-32)
- Removed effects section spacer (h-64/h-8)
- Automation lanes and effects now only in waveform column
- This eliminates the height mismatch between columns
3. Layout now cleaner
- Left column stays fixed with only track controls
- Right column contains waveforms, automation, and effects
- No artificial spacers needed for alignment
The automation lanes and effects sections now appear properly in the
waveform area without creating alignment issues in the controls column.

Restored the automation lane and effects sections that were removed during
the Track component refactoring. These sections now render as full-width
rows below each track, spanning across both the controls and waveforms columns.
Changes:
- Created TrackExtensions component for effects section rendering
- Added automation lane rendering in TrackList after each track waveform
- Added placeholder spacers in left controls column to maintain alignment
- Effects section shows collapsible device rack with mini preview when collapsed
- Automation lanes render when track.automation.showAutomation is true
- Import dialog moved to waveform-only rendering mode
The automation and effects sections are now properly unfoldable again.

Track controls now stay perfectly aligned with their waveforms during
vertical scrolling. The waveform column handles all scrolling (both
horizontal and vertical), and synchronizes its vertical scroll position
to the controls column.
Changes:
- Removed independent vertical scroll from controls column
- Added scroll event handler to waveforms column
- Controls column scrollTop is synced with waveforms column
- Track controls and waveforms now stay aligned at all times

Refactored track layout to use a two-column design where:
- Left column: All track control panels (fixed, vertical scroll)
- Right column: All waveforms (shared horizontal scroll container)
This ensures all track waveforms scroll together horizontally when
zoomed in, providing a more cohesive DAW-like experience.
Changes:
- Added renderControlsOnly and renderWaveformOnly props to Track component
- Track component now supports conditional rendering of just controls or just waveform
- TrackList renders each track twice: once for controls, once for waveforms
- Waveforms share a common scrollable container for synchronized scrolling
- Track controls stay fixed while waveforms scroll horizontally together
