/* Derived tokens RE-DERIVE at the room root (parley T24): a custom property
   is substituted at the element that declares it, so a ramp declared only on
   :root computes from :root's accent and a room-level override recolours
   half the system. Half a recolour looks deliberate, which is worse than
   none. check-parity.mjs vectors pin this. */
