   Olaf Minten Architectuur — shared design system
   styles.css · single source of truth for palette, type, spacing, motion
   and the site chrome (header/nav/footer) every page links to verbatim.

   Direction: light warm editorial ("architecture monograph"), derived from
   the reference tokens (accent oklch(68% .06 55) = #B08A66, radius .5rem,
   spacing .25rem, blur 8/12px) resolved against the shipped light render:
   warm paper canvas, near-black ink, hairline rules, one copper accent.
