/* ============================================
   PARASYN — CASE STUDIES STYLESHEET
   Metrics-forward, proof-of-delivery pages. Distinct from
   articles.css (long-form reading) and landing.css (sales pages):
   case studies lead with hard numbers and read like a dashboard
   readout, not prose. Each page sets its own --cs-accent custom
   property to give it a unique identity per customer/partner,
   while sharing the same structural system. Header/footer use
   the standard site.css.
