/* ============================================================
   CASE STUDY SYSTEM — portfolio/*.html
   Self-contained "cs-" component set. Every accent color below
   reads from --a / --b / --c / --grad (etc.), which each case
   study page re-declares on :root to its own project palette —
   so this single system re-skins per client while the page
   shell (nav, footer, type, motion) stays one DDebuggers site.
