/* BorderRelay — authentication pages.
   Moved out of the layout into its own stylesheet: the Content-Security-Policy
   forbids inline styles, and an external file is the correct answer to that
   rather than weakening the policy.
   Deliberately NOT merged into app.css: these pages use their own token names
   (--bg, --text, --primary) and merging two :root blocks would let one theme
   silently overwrite the other. Auth pages load this file and nothing else. */

   Auth pages follow the system preference; the stored user preference
   applies after login, in the application shell. */
