Momentum Carousel

Drag it, throw it, hit the end and it pulls back. One scalar is integrated per frame — friction, a rubber band past the last slide and an optional snap spring — and the track only ever gets a translate3d. Horizontal wheel nudges the rail; vertical wheel and touch keep scrolling the page. Switch the preset to crumble-hover and every hovered tile breaks into corner chunks.

drag · flick · shift-wheel · arrows — panel drives this rail

Engine: MomentumCarousel.init(el, options) → next() / prev() / goTo(i) / set() / refresh() / pause() / resume() / destroy(). The element's children become the slides, so any markup works. Artwork on these tiles is painted with 2D canvas at runtime — no image files, no network. With prefers-reduced-motion the inertia, snap spring and crumble twinkle are switched off; dragging still tracks your pointer exactly.
