   Candidate Atlas — site chrome.

   Roles, not colours, everywhere. Light and dark are stepped separately against
   their own surfaces and both passed the palette validator; dark is not an
   inversion of light. The three class hues (PLSI / frontier / control) are the
   same values the figure module uses, so a swatch here and a mark in the figure
   are literally the same colour.
