/* ============================================================
   bastian.css — Bastian public site
   ------------------------------------------------------------
   Bastian is the sibling product to PsiGuard, and this sheet
   is the deliberate sibling of PsiGuard's site.css: identical
   type scale, spacing, radii, shadows, components and SVG-icon
   style, so the two products read as the work of one team.

   The ONE intentional difference is brand colour — PsiGuard's
   purple/pink gradient becomes Bastian's blue/cyan. Everything
   else is shared on purpose. Class names match site.css
   (site-*, hero-*, section-*, triptych, feature, cta-strip)
   so markup ports cleanly between the two sites.

   Bastian-only additions live at the bottom (section 15):
   a numbered "how it works" sequence and a compact FAQ list,
   both built from the same tokens. Light-mode only.
