/* stamps.cl — UX 2026 · layer B (2026-09-27). Loaded LAST.
   1) Thematic taxonomy UI (chips, ficha band, hero, sidebar, gallery, editors).
   2) Ficha on phones: natural vertical scroll (the description and characteristics are always
      reachable; no tiny inner scroll box).
   3) Twelve new skins + per-visitor "scenario" options (card style, density, typeface, corners,
      motion) exposed as html[data-*] attributes by app.js.
   4) Phone catalogue: collapsible filters and a bottom navigation bar.
   Every colour comes from the theme tokens, so all skins, Senior mode and high contrast keep working. */
