/* Anmelden / Konto erstellen als eine Seite (2026-10-15). Aufbau: .fd-auth2 > .fd-auth2-card > .fd-auth2-stage mit zwei Bereichen (.fd-auth2-pane, Inhalt in
   .fd-auth2-inner) und dem dunklen Panel (.fd-auth2-overlay). Der Bereich "Konto erstellen" hat zwei Schritte (.fd-auth2-step): erst Name/E-Mail/Passwort, nach
   "Weiter" öffnet sich Schritt 2. Ohne Skript (kein .is-js) zeigt die Seite nur den Bereich der Adresse als einfache Karte, beide Schritte untereinander.
   Mit Skript: Computer (ab 900 px) = Bereiche nebeneinander, das Panel gleitet über die Karte; darunter = Umschalter oben, die Bereiche blenden über.
   Bewegung wie überall (motion.css): nur transform/opacity, kräftiges ease-out, bei "reduzierte Bewegung" ohne Übergänge. */
