- Fader handles now respect top-8 bottom-8 track padding - Handle moves only within the visible track lane (60% range) - Updated both TrackFader and MasterFader components - Value calculation clamped to track bounds (32px padding top/bottom) - Handle position mapped to 20%-80% range instead of 0%-100% - Prevents handle from going beyond visible track area 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
