 118/-- The three coupling formulas use distinct geometric constants:
 119
 120    - α uses the **11** passive edges (per-tick field dressing)
 121    - α_s uses the **17** wallpaper groups (2D crystallography)
 122    - sin²θ_w uses **(3 - φ)/6** (φ-based prediction)
 123
 124    These are all forced by RS structure, not fitted. -/
