- Add rotateY axis (drag left/right rotates Y, up/down rotates X)
- Shift+drag for Z-axis roll
- Remove 10-80° clamp on rotateX — full ±180° range
- Remove backface-visibility:hidden so layers visible from all angles
- Fix overflow:hidden → overflow:visible for proper 3D perspective
- Increase layer spacing 80→120px for more dramatic depth
- Increase viewport height 340→420px, perspective origin centered
