   Same editorial system as styles/case-study.css. No frameworks, no
   webfonts, no CDN, no build step.

   Tokens and shared primitives (.wrap, .section, .eyebrow, .prose,
   .points, .btn, .foot ...) are mirrored from case-study.css on
   purpose: the approved case study is left byte-for-byte untouched, so
   this file carries its own copy. If a token changes here, change it
