        frame_data,  # UT3Frame .data (an orthogonal frame), supercore stack = C
        ww,          # apply vectors, len=d, ith elm_shape=W+(Ni,)
):  # -> uniform apply frame sweep: (masked_frame, packed_ww, shape, (xis, mus))

The all-modes apply frame sweep for the uniform tangent Jacobian: mask-once the frame, pack ww to the supercore mode width N, and precompute the lean (xis, mus) via the polymorphic apply.tv_precompute_apply_frame_sweep(). The reuse hook for the uniform fitting inner solve.
