T3Frame.reverse =============== .. py:method:: t3toolbox.frame_variations_format.T3Frame.reverse() .. code-block:: python def reverse(self) -> 'T3Frame': Reverse the mode order. Left/right cores **swap roles** (reversing a left-orthogonal chain yields a right-orthogonal one), so ``new_left = reverse(old_right)`` and vice versa; the redundant L/R store makes this exact with no re-orthogonalization.
