/* ============================================================
   site.css — PsiGuard public site
   ------------------------------------------------------------
   External stylesheet for the marketing / public-facing
   surface (currently: index.html). Designed to coexist with
   chat.css and dashboard.css without collisions — class names
   are prefixed (site-*, hero-*, section-*, etc.) and CSS
   variables are scoped at :root with PsiGuard tokens that
   match the existing visual language.

   Design intent: ClearScope-style editorial layout — full
   width, generous whitespace, big type, alternating text /
   screenshot sections — but in PsiGuard's existing brand
   palette (purple/pink gradient, slate, DM Sans). Light-mode
   only for now; the app surfaces handle their own themes.
