   Oben links Routesetting, oben rechts Webdesign, darunter das Dreieck für

   die Facetten des Logos als Raster.

   Unter 48rem stehen die Panels untereinander. Ab 48rem liegen alle drei
   deckungsgleich übereinander und werden per clip-path zugeschnitten.
   Die Nähte zeichnet .split__seams in index.html; der Pfad dort nutzt
   dieselben Werte (50 / 40) und muss bei einer Änderung mitgezogen werden.
   Beim Hover verschiebt main.js (SPLIT_NODE) den Knotenpunkt und schreibt
   Zuschnitt und Nähte während der Bewegung gemeinsam in Gerätepixeln. */
