One angle encodes Moho boundary AND water geometry
θ_SiO₄ = 1080/π² degrees = 6/π radians. Identity: θ_SiO₄ = (π/3)×θ_HOH [exact]. Chain: θ_SiO₄/3 (rad)×10⁷ = R_Moho = 20,000/π km [0.000 ppm]. One angle, three domains.

Key Results
θ_SiO₄ = 1080/π² = 6/π radians. θ_SiO₄ = (π/3)×θ_HOH [exact]. θ/3 × 10⁷ = R_Moho = 20,000/π km.
Oceanic crust ≈ 7 km sits off the stable {2,3,5} thickness nodes → always subducted. Continental crust 40 km = 2³×5 → permanently stable. Only a clean {2,3,5} node achieves lattice lock.
Outer core Vp: CMB 2³=8, mid 3²=9, ICB 2×5=10 km/s. Prime succession {2}→{3}→{5} with depth.
Core pressures: CMB 3³×5=135 GPa; ICB 2²×3⁴=324 GPa. Ratio = 12/5 = 2²×3/5 — pure {2,3,5}.
Thorium Z=90=2×3²×5 — only major radiogenic element with pure {2,3,5} atomic number.
