/* ---------------------------------------------------------------------------
   Design tokens.

   Colours come from the dataviz reference palette, unchanged, and the dark
   column is the same hues re-stepped for the dark surface - not an automatic
   inversion. The categorical slots in use are validated as a set:

     light  #2a78d6 #eb6834 #1baf7a   all-pairs PASS (surface #fcfcfb)
     dark   #3987e5 #d95926 #199e70   all-pairs PASS (surface #1a1a19)

   Light-mode aqua sits at 2.74:1 against the surface, below the 3:1 line, so
   wherever it carries meaning the value is also written out or present in a
   table - the relief rule, not an oversight.

   Dark values are declared twice on purpose: once under prefers-color-scheme
   for the OS setting, once under .theme-dark for the in-page toggle, so the
   toggle wins in both directions.
