HoloCell — Mode 10: Vogel (Crystal Harmonic Resonance)

Based on Jain 108's diagram:
- SPINE: Vogel crystal (24 sides, 52°/60° angles)
- NETWORK: Truncated icosahedron (60 vertices, buckyball)
- FIELD: Toroidal resonance from poles

The truncated icosahedron (Archimedean 5,6,6):
- 60 vertices
- 90 edges  
- 32 faces (12 pentagons + 20 hexagons)
- Each vertex connects to exactly 3 others

This is C60 (buckminsterfullerene) — nature's own stable geometry.

The spine is the axis. The buckyball is the network.
Coherence radiates from spine through the geometric constraints.
