One engine, four personalities. The element's children become the slides;
[data-media] is the visual and [data-copy] is the text block.
Pick a preset in the panel — it tears the slider down and rebuilds it in the new mode.
Drag the slides, use the arrows and dots, or focus the carousel and press
← / →. Autoplay pauses while you hover, while the carousel
holds focus, when it scrolls off-screen and when the tab is hidden.
