      def frames_equal(data1, data2, rtol=None):


   Numerical equality of two frames given as nested core tuples (e.g. ``T3Frame.data``).

   The honest "same tangent space" test: two frames are the same iff their cores are equal. It accepts
   the value-equal-but-different-object frames a jit round-trip produces, while rejecting a genuinely
   different frame. ``rtol`` defaults to the ambient jax-aware tolerance (falling back to the defaults if
   unsafe -- this is a pure comparison, mode-agnostic).
