A striking way to show social proof. Testimonial cards fan out in 3D around a highlighted center card that has a notched corner and a bold offset shadow. Bring any card to the center by clicking it, using the arrows or arrow keys, or dragging. It auto-advances and pauses on hover or focus, and adapts card size on smaller screens. Ships as a single self-contained file (injects its own CSS, no Tailwind required), works in light or dark, React 19 + TypeScript strict, accessible and reduced-motion aware.

The bento pattern every landing page wants, with real polish: on hover the content lifts, the icon shrinks to the corner and the CTA slides in. Our twist — a spotlight that follows the cursor tinted to each card's accent, plus an accent hairline that draws across the top. Each card takes a `background` slot (images or animated layers), a per-card accent color, spans 1–3 columns and supports light/dark. Zero dependencies — no Tailwind, no radix, no shadcn. One file, works anywhere React runs.
