/* pc-baukasten/styles.css
   Die Oberflaeche der PC-Baukasten: Werkbank (3D), Listen, Monitor-Fenster,
   Auftrags- und Ergebnis-Karten, Info- und Hilfe-Box.

   Wichtig fuer beide Themes: die Flaeche INNERHALB der Werkbank (.pcb_stage) ist
   absichtlich immer dunkel (Werkstatt-Optik) und traegt daher feste helle
   Schriftfarben. Nur die Kaesten UNTER dem Spiel (Info/Hilfe) richten sich nach
   dem Theme - so kann nie helle Schrift auf hellem Grund entstehen. */
