/* Singoldwerk – Demo "Fliesen Muster"
   Reines CSS, keine externen Ressourcen, keine Webfonts.
   Viertes eigenständiges Rasterprinzip: warmes Sandbeige + tiefes
   Graublau, ruhige, helle Typografie mit viel Weißraum, Karten als
   "Fliesenraster" mit duennen Fugenlinien statt Rundungen (Dachdecker),
   scharfer Zeilen (Elektro) oder Tag-Karten mit Akzentkante (Kfz). */
