Other Lattice
Track BBanana Curve. Harmonic nodes. Morié gears. E8 / C60 / Venus rose.
Geometry
E8 has 240 roots. C60 is the truncated-icosahedron fullerene. The Venus rose is the 8:13 synodic tracing. Banana Curve and Morié gears are study diagrams for interference, not machines to build.
Use
Layer B/C. Never a court exhibit. Euclid’s angle-deficit proof of the five Platonic solids remains the clean geometric core (Book XXVII).
