ufv_reciprocal_weights
======================

.. py:function:: t3toolbox.backend.ufv_operations.ufv_reciprocal_weights(weights)

   .. code-block:: python

      def ufv_reciprocal_weights(weights: UT3FrameWeightsData) -> UT3FrameWeightsData:


   Elementwise ``1/w`` on the real slots of all four families (masks unchanged); the padding stays a
   canonical, **finite** zero rather than becoming ``inf``. See ``ut3_reciprocal_weights`` -- this is the
   Grasedyck-Kramer path (``from_ut3weights(from_ut3svd(x)).reciprocal()``), so the guard is on the
   headline route. Real-slot zeros are deliberately NOT guarded.
