/* ==========================================================================
   Spielidee Block — strukturelle Basis-Styles (keine Panel-Werte)
   Technische Basis 1:1 vom Testimonials-Block übernommen (Overlay-Mechanik,
   Scroll-Lock, Vignette-Schrumpfeffekt), Klassen auf "si-" umbenannt und um
   Grid-Modus, bildlose Karten und Overlay-Galerie erweitert.
   Karussell-Modus läuft jetzt über Swiper statt eigenem Drag-Code.
