/**
 * The Web ID NRW – gemeinsame Carousel-Stile (Bilder- und Logo-Carousel) + Lightbox.
 *
 * Steuerung über CSS-Variablen am Wurzelelement (vom Block gesetzt):
 *   --twid-pv / --twid-pv-t / --twid-pv-m   Slides pro Ansicht: Desktop / Tablet / Smartphone
 *   --twid-gap                               Abstand zwischen den Slides
 *   --twid-peek                              Sichtbarer Anschnitt der Nachbar-Slides links/rechts
 *   --twid-radius                            Eckenrundung
 *
 * Aufbau:
 *   .twid-carousel                 Wurzel (Container für Container-Queries)
 *     .twid-carousel__stage        Bereich mit Slides und Pfeilen
 *       .twid-carousel__viewport   Horizontal scrollbar, Scroll-Snap
 *         .twid-carousel__track    Flex-Reihe (ul)
 *           .twid-carousel__item   Slide (li)
 *       .twid-carousel__arrows     Pfeile (von carousel.js erzeugt)
 *     .twid-carousel__controls     Pause-Button + Punkte/Zähler (von carousel.js erzeugt)
 *
 * Die Breakpoints beziehen sich auf die Breite des Carousels selbst
 * (Container-Query) – ein Carousel in einer schmalen Spalte zeigt also
 * automatisch weniger Slides.
