/* ==========================================================================
   BIMI Validator Engine — CIO Factory
   Design system: orient-luxury (near-black + grain, gold accent, parchment
   light mode). Token source: portable orient-luxury-core.css pattern,
   inlined here until the shared snippet is wired in via <link>.

   Signature element for this app: a wax letter-seal that presses down onto
   the result card and reveals an embossed mark — gold for a verified BIMI
   record, oxblood for one with issues, plain wax for no record found. BIMI
   is literally a domain's visual seal of authenticity in the inbox, so the
   historical letter-seal metaphor is the app's own subject matter, not a
   decoration borrowed from elsewhere. A secondary inbox-row preview shows
   the practical payoff: how the logo actually renders next to a sender.
