/* Version 0.42: Start-Dialoge (Sprachfrage, Sprachwahl beim Erststart, Willkommen) – groß, freundlich, mit Bewegung.
   Markup: js/ui/startdialog.js, Dialoge in js/main.js (groesse "start" → .modal-start). Alle Zeiten, Kurven und Wege kommen aus den
   Tokens von css/wizard-motion.css (--motion-*, --ease-out, --stagger-step); animiert wird nur transform, opacity und (einmalig) das
   Zeichnen der Linien. `html[data-motion="aus" | "reduziert"]` und `prefers-reduced-motion` schalten die Bewegung ab. */
