/* ============================================================================
   public.css — the public marketing site's component & layout system.
   ----------------------------------------------------------------------------
   The public site is its OWN lightweight surface (no app shell), but it shares
   the SAME design-token source of truth as the console: it links
   /console/static/tokens.css and consumes ONLY var(--token) here. There is not a
   single hardcoded colour, font, radius or ad-hoc spacing value in this file —
   change tokens.css (or design.md) and the public site re-skins with the app, so
   the marketing site and the product are visibly one brand.

   Self-hosted only: fonts come from tokens.css @font-face (no Google Fonts, no
   external CDN, no analytics, no trackers).
