/* --- NOTE ON --divergent -------------------------------------------------
   design_tokens_v2_0.yaml maps `divergent` and `needs_verification` to the
   same hex (#B45309). Two distinct states sharing one colour is a defect the
   non-colour channel merely survives. `divergent` is set here to #92400E
   (5.74:1 on the content canvas) so the two are separable. Raise back into
   the token file at the next revision — this file must not become the second
   source of truth.
