/* ---- Marquee / Marken-Laufband ------------------------------------
   Logo-Chip-Design: jedes Logo sitzt in einem hellen, abgerundeten
   Plättchen und behält seine Originalfarben. Das funktioniert
   einheitlich für transparente UND hintergrundbehaftete Logos
   (z. B. idealo, Opera, Saily) – kein Weiß-Filter, der Logos mit
   eigenem Hintergrund in weiße Klötze verwandelt.
   Standard leicht entsättigt, beim Hover volle Farbe + Anheben.        */
