// 4. SHIFT NORMALIZATION
// =============================================================================
// Purpose:
//   The absolute values of sin^2(theta_W) and sin(theta_C) differ, but their
//   geometric dependence on N can be compared directly by aligning both curves
//   at the physical lock-in point N_final. The shift is purely a visualization
//   tool and does not alter the underlying physics.
//
// Shift applied:
shift_C = sin2W_at_Nfinal - sinC_final;
sinC_shifted = sinC_results + shift_C;
