/* Two "text on a fill" tokens, deliberately separate:
     --on-accent  goes on a --accent fill
     --on-green   goes on a --green-solid fill
   They are NOT interchangeable. A consumer whose accent and green are the
   same hue can point both at one value; a consumer whose accent is blue and
   whose green is dark cannot — one value that passes on one fill fails on
   the other. Collapsing these into a single token silently regressed a
   consumer's date picker from 4.93:1 to 3.83:1, below AA. */
