/* ============================================================
   AEQUIVIO — public homepage design system (2026 redesign).
   Grafts the elevated marketing layout onto the ESTABLISHED brand:
   same palette as landing.css (ink #0a1130 · bg #fbfcff · indigo→
   violet→blue gradient), brand serif wordmark, NO external web fonts
   (CSP has no font-src → Google Fonts are blocked; we use the same
   system stacks the rest of the site already uses). Self-contained:
   this page does NOT load portal.css, so none of landing.css's
   token-collision caveats apply here.
