/* ============================================================
   case.css: shared layout for the case study STORY pages
   (first used by case-studies/cgiar.html, 2026-10-05).

   Built to be reused: a page picks its accent with one class on
   <body>: case--cgiar | case--xymbia | case--marham | case--ds.
   That sets --case (accent: highlighted words, lines, markers) and
   --case-tint (soft section backgrounds).

   Every colour comes from css/colors.css. Fonts (2026-10-06): Fraunces
   400 for display, Instrument Sans for everything else. No italics.
   Raspberry is NOT used on case study pages: links, ticks and the
   progress line are near-black (Arwa, 2026-10-06).
