/* Austria Energy Group – Anfragestrecken im Gesprächsformat.
   Aufbau, Maße, Schrift und Abläufe folgen Frage für Frage der Vorlage der
   Quell-Website (WPForms Conversational Forms, Farbschema „hell“): Titelseite
   über die volle Höhe, danach eine Frage nach der anderen mit Buchstaben-
   tasten für die Antworten und einer festen Fortschrittsleiste unten.

   Zwei bewusste Abweichungen von der Vorlage:
   – Knöpfe tragen das Markenblau statt des Vorlagenblaus.
   – Gedämpfte Texte sind so weit abgedunkelt, dass sie den Kontrast von
     4,5:1 erreichen; die Vorlage bleibt dort unter dem Mindestwert. */
