   White-dominant palette. Green and yellow appear as type, hairline rules,
   buttons and one highlighter — never as large filled fields. Both hues are
   sampled from the BMD wordmark.

   Deliberately single-theme: the page is white for every visitor, whatever
   their system setting. Token groups:
     core    — ink, body, line, surfaces
     field   — the hero / page banner / footer bands
     mark    — the yellow highlighter, which only works under dark text
