/* Kartenwert - Oberflaeche
   Gestaltungsidee: Sammelalbum bei Nacht. Tiefes Tintenblau als Grund, Karten
   liegen wie in Albumtaschen auf leicht angehobenen Flaechen. Einzige
   Schmuckfarbe ist ein warmes Foil-Gold fuer Werte und Hauptknoepfe; Gruen/Rot
   nur fuer Wertaenderungen. Zahlen tabellarisch, damit Euro-Betraege
   untereinander stehen. Folgt dem Hell/Dunkel-Modus des Handys. */
