   Farbwerk — Template für Maler- und Ausbaubetriebe
   Ein einziges Stylesheet. Keine CDN-Abhängigkeit, keine Webfont-Ladung,
   keine JS-Abhängigkeit für Layout oder Lesbarkeit.

   FARBEN UND SCHRIFTEN ANPASSEN: ausschließlich im :root-Block unten.
   Eigene Webfonts: woff2 nach /fonts/ legen und hier @font-face ergänzen,
   dann --font-sans überschreiben.
