270 271/-- **Geometric Origin of Jarlskog Invariant** 272 The Jarlskog invariant J_CP is the geometric area of the unitarity triangle, 273 forced by the cube topology and the fine-structure leakage. 274 J = s12 s23 s13 c12 c23 c13 sin δ 275 Approximated geometrically as: 276 J ≈ (1/24) * (α/2) * (φ⁻³) * sin(π/2) -/
