/* KW Atelier – Partner-Slider (Phase 4, Schicht 1). Endloses Logo-Laufband für
   Partner & Kooperationen. Die Logos laufen ruhig in Graustufen und leuchten bei
   Hover in Farbe auf; Gold-Pfeile, Pause/Play (WCAG), Hover-Pause. Über die
   Mediathek wählbare Zicklinde als Gastgeberin am Bandrand oder neben dem Titel.

   Das Laufband ist eine CSS-Animation (läuft auch ohne JS); das JS-Modul ergänzt
   nur Pause/Pfeile/Klon-Auffüllung. Farben aus Tokens; lokale --kwat-ps-* mit
   Marken-Fallback, vom Stil-Tab überschreibbar. Regeln: includes/Widgets/CLAUDE.md.
   Kein !important. */
