   CASE STUDIES PAGE (/case-studies/)
   Builds on main.css tokens. Each case sets --accent / --accent-soft
   inline in the client's own brand colour, the same way the reports do.

   Scroll animations are armed by case-studies.js on the visitor's first
   scroll (it adds .cs-anim to <html>). Crawlers never scroll, so they
   never see a hidden state and every line of copy stays visible text.
