.. py:module:: t3toolbox.backend.ufv_operations

.. autoapi-nested-parse::

   Stateless stack/unstack for the uniform frame-variations layer (UT3Frame / UT3Variations).

   Mirror of ``ut3_operations.ut3_unstack`` / ``ut3_stack`` for the bv ``.data`` layout
   ``(*supercores, shape, masks)``, generic over the supercore count (4 for a frame, 2 for variations;
   both carry the SAME 4-tuple of rank masks). The stack lives at axes ``1 .. len(stack_shape)`` (axis 0 is
   the mode index ``d``, NOT a stack axis); the supercores and all four masks unstack along it, while the
   int-tuple ``shape`` is shared and woven onto every leaf. The masks' differing leading axis (``d`` vs
   ``d+1``) is irrelevant -- only axes ``1..k`` are sliced.
