   Raw colour values. Theme-independent, surface-independent.
   Never reference these from a component: components read the
   semantic tokens in base/_surface.css instead.

   Rungs are assigned by measured CIE L* lightness, so <family>-500
   is the same brightness in every ramp and ramps are swappable.

   Ramps not yet in use live in _palette-reserve.css.
