   Signature element: the "Clearance Badge" — a hexagonal verification seal
   used on team credentials, testimonials, and certifications, echoing the
   agency's vetting process. Paired with a "manifest strip" (mono, tracked
   uppercase, tick-divided) used for trust signals — the visual language of
   an ID card / clearance document.
