      def randn(
              self,
              frame:        ubv.UT3Frame,
              stack_shape:  typ.Tuple[int, ...] = (),   # extra tangent stack K (a batch of tangents)
      ) -> UT3Tangent:  # gauged random tangent at frame


   Random tangent at ``frame``: a standard Gaussian on the tangent space ``T_xM``.

   Raw i.i.d. ``N(0, 1)`` variation supercores, then the gauge projection :py:meth:`project` (``Pi``).
   For an orthogonal, minimal-rank ``frame`` this is the standard Gaussian on ``T_xM``. ``stack_shape``
   is the extra outer tangent stack ``K`` (default ``()``). Inherits :py:meth:`project`'s safe-mode ORTH
   precondition (a non-orthogonal ``frame`` raises; skipped under ``safety.unsafe()`` / a jax trace).
