   The geometry at ``x0``'s fixed rank. The variation masks come from ``x0``'s orthogonal
   representation (:py:func:`~t3toolbox.backend.ufv_conversions.ut3_orthogonal_representations`),
   which is where the SVD-prefix mask contract is established -- do not build them by hand
   (``docs/contributor/uniform_svd_prefix_orthogonalization.md``).
