/* California Boundaries: a county-sorting game on brand.css tokens and ui.css,
   laid out as Benefit Cliffs is.

   The three regions are the brand blue (NorCal), a green (Central) and the brand
   orange (SoCal), measured in both themes: each is 5:1 or more against the card,
   and any two are 88 or more apart (CIE Lab), so the colors stay apart wherever
   counties meet; simulated for deuteranopia and protanopia they stay 32 or more
   apart (Central and SoCal are the closest pair). None is the site's purple, which marks controls: the pressed
   brush and the focus ring. Neighboring counties are split by a line in the
   card's color; an unsorted county is a quiet gray with an edge. Color is never
   the only cue: the status line names the county and its region, and the results
   table gives every share. */
