/* ftf brand overlay for /log-in/ and /sign-up/.
   Loaded AFTER auth.css so it overrides palette + typography while leaving
   the structural class names (auth-shell / auth-card / auth-field / ...)
   identical. The shared JS in /auth/auth.js depends on those class hooks
   — they MUST stay. Style only. */
