Paper 12 of the Holographic Cosmology Series. Derives two fundamental results from one geometric rule: (1) the Born Rule Pᵢ = |cᵢ|² as a boundary-area fraction from Hooke's law on the elastic Planck-tile membrane; (2) the Weinberg angle sin²θW = 3/13 from the consistency condition ν = 1/ (12 sin²θW) with Poisson ratio ν = 13/36.
