/* SmartMaic Dashboard
   Mobile-first. Ein Stylesheet, ein Satz Templates. Schmale Screens
   bekommen die Basis (einspaltig, grosse Zahlen), ab Breakpoints wird
   auf mehrspaltiges Desktop-Layout erweitert. Begruendung in der README:
   ein responsives Codebase ist wartungsaermer als getrennte Templates. */
