   DESIGN TOKENS
   Copied verbatim from the Alaasmagi design system so this site
   is fully self-contained — it does NOT import from or depend on
   the /alaasmagi-design-system folder. To rebrand the accent,
   change the hue value (229) in the six --accent-* lines and the
   two --text-link* lines; everything downstream re-colors.
