/* Neue Frutiger World — selbst gehostet.
   Die @import-Zeilen auf use.typekit.net und fonts.googleapis.com sind

   CSP-Eintrag, eine Datenschutzfrage und ein Ladezeit-Posten.

   ACHTUNG LIZENZ: Die Dateien liegen NICHT im Repository und duerfen
   nicht aus dem Adobe-Fonts-Projekt qhi0jrm herausgezogen werden -
   Adobe Fonts erlaubt kein Self-Hosting. Die drei Schnitte brauchen
   eine eigene Webfont-Lizenz von Monotype. Erst dann die Dateien unter
   resources/fonts/ ablegen; siehe resources/fonts/README.md.

   Solange sie fehlen, greift die Ersatzkette in --font-ui. Die Seite
   bleibt vollstaendig benutzbar, sieht aber nicht nach Marke aus. */
