Browser ONNX inference predicts nodal displacement DOFs for the right and left sole meshes.
Pressure is evaluated on bottom Quad4 contact points:
p_q = k_c * max(0, delta_q - u_y,q), then area-weighted back to the mesh.
One-foot NN inference time:
-- ms
per ONNX call, so the max serial rate is
-- Hz.
