   Case studies — the index
   The breakout page behind the site's secondary CTA. Layered over site.css;
   same tokens, same motion grammar, nothing here overrides the shared system.
   Lives under /css/ rather than beside the page because vercel.json redirects
   /molly_report/case-study/:slug onto a trailing slash, which would swallow a
   stylesheet sitting next to the index.
