   The token names and values below mirror app/static/css/skins/register.css

   Role map, enforced throughout:
     ranger green = action and selection ONLY
     deep ocean   = place, weather, map relationships
     neutrals     = structure
     semantic     = status
   Never swap these for visual variety.
