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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
