First physics enhancement - shadow changes based on how fast you drag:
- Tracks drag velocity (distance/time) during pointer move
- Shadow grows larger and darker with faster dragging
- Base: 8px offset, 24px blur, 0.3 opacity
- Fast: 32px offset, 64px blur, 0.6 opacity
- Smooth decay when released
Console logging included:
- [Shadow] logs on drag start/release
- Speed/distance/time logged during drag (throttled to ~100ms)
Test: Drag cards slowly vs fast and watch shadow change
