/* ================================================================
   Friendly Auth — the sign-in / sign-up / password screens.

   Layout borrowed from nextbard.com: a brand column beside the card,
   a segmented switch instead of a buried "no account yet?" link, and
   monospace for anything the machine produced.

   Colour comes from the landing page instead — the same tokens the
   .lf block in index.html declares, so a coach who clicks "Sign in"
   in the header does not walk into a different product. Sky ground,
   white cards, one indigo brand, Bricolage headings.

   Scoped entirely under #authPage. The only DOM this file needs
   beyond auth.css is .auth-brand and .auth-segs, both rendered by
   js/auth.js (see brandPanel() and modeSwitch()).
   ================================================================ */

     inside, so those variables cannot be inherited. Nearly all of them are
     the same values style.css already publishes on :root, so we point at

     the fallbacks, and the two tokens below that carry no :root twin. */
