   MeetApp – Gestaltungsgrundlage

   Alles, was mehr als eine Seite betrifft, steht hier: Farben und Abstände als Variablen,
   die Anpassungen an Bootstrap (Knöpfe, Formularfelder, Karten) und die Bewegungsmuster
   (Einblenden beim Scrollen, Zähler, Nach-oben-Knopf), die site.js ansteuert.

   Seitenspezifisches gehört weiterhin ins Scoped CSS der jeweiligen Komponente.
