The Media Carousel node is an interactive message type (Meta carousel): up to 10 cards, each with image/video, title, body (e.g. 160 chars), and up to 2 buttons (quick reply or URL). You configure body message, cards, and buttons. The node has one output port per quick-reply button (e.g. card_X_btn_Y) for routing. Test Journey supports carousel display (horizontal scroll, dot indicators). Use it for product catalogs, options, or menus.
