Infinite card loop with depth: the active card is big with a glowing outline, the cards beside it shrink and fade, and the ring wraps without a jump. Controls: Prev and Next buttons, arrow keys, swipe or drag, and optional autoplay that pauses on hover and focus. A short vanilla script sets an offset variable on each card; all the looks are CSS. Card component props: number, label, title, text, tone. Options: data-autoplay (off|on) and data-speed (calm|normal|snappy). Options (data attributes on the section): data-theme (light|dark) surface behind the cards; data-anim (rise|fade|none) entrance; data-autoplay (off|on) advance automatically; data-speed (calm|normal|snappy) animation speed; data-glow (on|off) outline glow on the centre card.
