   F-015 — Premium Detail-Page Design System
   Shared language for ALL individual/detail pages. Namespaced `dp-` to
   avoid collisions with legacy styles. No framework required.
   Hero patterns: A editorial / B service / C media / D creative /
                  E showcase / F corporate.
   Brand accents driven by layout body classes:
     .ms-section  -> studio (magenta/violet, dark)
     .deb-section -> editorial (crimson + ink)
     .pat-section / .pat-testing -> trust (navy + amber)
     default (main) -> corporate (navy + gold)
