/* AP-15 / AS-04 - Buchungsbaustein fuer Kundenwebsites.

 * Alles ist unter .hkb gekapselt. Schrift kommt von der Website (inherit), die ruhige Papierflaeche
 * bleibt auch auf dunklen Vorlagen lesbar. Einzige Markenfarbe ist --hkb-accent (Website-Akzent oder
 * eigene Farbe aus dem Konfigurator); die Schrift darauf waehlt das Script nach Kontrast.
 * Keine Webfonts, keine externen Ressourcen.
