ManifoldGeometryOps.inner
=========================

.. py:method:: t3toolbox.backend.geometry.ManifoldGeometryOps.inner(a, b)

   .. code-block:: python

      def inner(self, a, b):


   The coordinate ``<.,.>`` on tangents (Hilbert-Schmidt on an orthonormal, gauged frame),
   **per-element over the leading stacks** (``K+C``) -- shape = stack, a 0-d scalar unstacked,
   matching the uniform twin and the frontend ``MANIFOLD.inner`` (review H3-5).
