   .. code-block:: python

      def is_orthogonal(self, atol: float = 1e-9) -> NDArray:  # bool array, shape = stack_shape (scalar unstacked)


   True (per stack element) if the frame supercores are orthogonal in their respective senses on
   the real (masked) content. Per-element bool array (reduce with ``.all()`` for a single verdict);
   verified against the ragged oracle ``to_t3frame(self).is_orthogonal()``.
