Module response_geometry 

Exact shared-smoothing Gaussian REML for tangent-vector responses.

The model has a scalar predictor design X (N x K) and a tangent response Y (N x D). A coefficient matrix B is fitted under

sum_i w_i (y_i - B' x_i)' M_i (y_i - B' x_i) + sum_b lambda_b tr(B' S_b B).

The implementation deliberately never constructs the stacked (N D) x (K D) design or a S_b (x) I_D penalty. Isotropic metrics use only K x K normal equations. Varying Fisher metrics stream exact joint sufficient statistics into a (K D) x (K D) Gram matrix whose storage is independent of N.
