/* ============================================================
   BlueTeamAutomation — shared brand chrome (nav + footer mark)
   Loaded AFTER each page's inline <style> so it overrides the
   legacy nav. Mirrors the homepage's refined header exactly.

   Every var() carries a brand fallback so the header renders
   identically even on pages whose :root omits some tokens
   (e.g. legal/faq pages that only define a subset).
