/* Probative — marketing site, v4 "Certificate Edition".
   Conviction: the security-printed certificate. Guilloché engraving is
   anti-tamper printing — which is the product. White ground, fine cobalt
   line fields, engraved figure art, pill nav + gradient-rim CTAs, pastel
   bento cards, dark-navy rounded billboard bands (Plaid structural DNA,
   our identity). Space Grotesk display at medium weight / tight tracking;
   Fraunces serif kept for numerals + the italic counter-voice; JetBrains
   Mono for exhibit labels. Motion stays stop-motion: steps() frames,
   three-depth parallax — never a glide. Double-guarded reduced-motion. */
