/* ==========================================================================
   DESIGN TOKENS
   Palette: Ledger Navy (primary/authority), Paper (ground, certificate stock),
   Seal Green (verified/accent), Gold Foil (credential/premium marks),
   Ledger Gray (body text), Alert Red (errors only).
   Type: Cinzel (display — carved/inscribed, reads like a seal) used sparingly;
   Work Sans (body/UI — plain, legible, does the daily work);
   IBM Plex Mono (data face — for DUNS numbers, UPCs, codes, dates: anything
   that is literally a credential or a figure, set in a face that looks issued
   rather than written).
   Signature element: a barcode rule — a thin, code-128-style bar pattern used
   as a section divider, standing in for the UPC/GPL work at the center of the
   business. Also a circular "seal" mark used to stamp verified claims.
