/* ============================================================
   Landing page (ui-redesign/index.html) — hero, how-it-works,
   sample strip, trust, FAQ, pricing. Reuses .btn/.chip/nav/footer
   grammar + tokens from styles.css (foundation commit ff7d6b8).
   Sample-strip cards render via the real .tile-card grammar
   already defined in styles.css — only container/scroll layout
   for that strip is defined here (PORT-CONTRACT.md decision 1).
