   Public sites — DESIGN.md "Deep colour, gold and serif" (2026-11-02, after the user's reference fcms.kln.ac.lk)
   Loaded by includes/header.php after style.css, so it themes the faculty site and every unit's public pages and never
   the portals. Colours come only from the unit variables (--primary, --primary-dark, --accent, --accent-light) and the
   tokens below; deep grounds are color-mix()ed from --primary so each unit stays in its own colour.
