/* Loggad — public site styles (hand-written, committed).
   Consumes ONLY the design tokens from /brand/design (a build-time copy of
   loggad.client/src/assets/design — the single source of truth). No literal
   colours or fonts here; sizes are tokens except layout plumbing (the phone
   frame's proportions, hairlines). If a value is missing, add a token in the
   client design system, not a literal below.

   Themes: /js/theme-boot.js sets html[data-theme] to "light" or "dark" from
   prefers-color-scheme before first paint, so theme.css's
   :root[data-theme='dark'] overrides apply exactly as they do in the app.
   Without JavaScript the page renders the light theme.

   The production CSP is style-src 'self': no inline style attributes anywhere
   in the markup. */
