/*
 * Bilder-Rätsel – cleanes Schwarz-Weiß-Theme
 *
 * Neutrales, modernes Design, das sich an den ODAS-Basis-Look anpasst (auch
 * ohne branding.css): weiße Karten, dunkle Schrift, dezente graue Linien und
 * Schatten. Farbe nur dort, wo sie eine Funktion hat (grün = richtig,
 * rot = falsch). Selektoren, die mit der zur Laufzeit injizierten branding.css
 * (button/.btn/h1-h6) kollidieren, sind unter #main-content gescoped.
