.. py:method:: t3toolbox.uniform_manifold.UT3Tangent.tangent_stack_shape()

   .. code-block:: python

      def tangent_stack_shape(self) -> typ.Tuple[int, ...]:


   Tangent stack ``K``: the extra *outer* batch of tangent vectors sharing this frame.

   The part of the variation stack that exceeds the frame stack (often empty). The variation
   supercores are stacked ``(d,) + K + C + (core,)`` -- extra axes outermost, frame stack inner.
