/* stephenshaffer.io — "Field notes"
   Palette: paper #F2EFE3 · ink #1B2620 · green #3B5D45 · clay #9C4A24

   Every text colour below clears WCAG AA (4.5:1) against --paper, and the
   greys stay ordered ink > body > soft > muted > faint > fainter so the
   hierarchy still reads. Do not lighten them back: the quiet tone comes
   from size, weight and letter-spacing, not from low contrast.

   Ported from the Claude Design project (direction 1a). Two deliberate
   deviations from the design source, both forced by deployment config:
   1. asset URLs are root-absolute, because vercel.json sets cleanUrls
      and pages are served from more than one directory depth;
   2. the utility classes at the foot of this file exist so no shipped
      markup needs an inline style= attribute — the CSP in vercel.json
      sets style-src 'self' with no 'unsafe-inline'. */
