## JavaScript
```js
(() => {
  const root = document.querySelector('.card-16');
  if (!root) return;
  const c = root.querySelector('[data-card-16="root"]');
  if (!c) return;
  c.addEventListener('mousemove', (e) => {
    const r = c.getBoundingClientRect();
    c.style.setProperty('--card-16-x', `${e.clientX - r.left}px`);
    c.style.setProperty('--card-16-y', `${e.clientY - r.top}px`);
  });
})();
```

How this works

A radial-gradient overlay follows the pointer around the card face. A short JS handler reads the pointer's position on mousemove, normalises it to percentage coordinates, and writes --x and --y custom properties into the card's inline style.

The overlay is a pseudo-element with background: radial-gradient(circle at var(--x) var(--y), rgba(255,255,255,0.15), transparent 40%). Wherever the pointer sits, that spot glows.

At rest the overlay's opacity is zero; on :hover it fades in via a transition: opacity 200ms. On mouseleave, opacity fades out — the spotlight doesn't leave a residual glow.

Make it yours

  • Change spotlight size via the radial-gradient's stops — closest-side for a small hotspot, 200% for a wide diffuse glow.
  • Rebrand spotlight tint from white to the card's accent — rgba(124,108,255,0.2) gives a violet glow.
  • Tune fade-in and fade-out durations independently — 150ms in for responsiveness, 400ms out for a graceful trail.
  • Add a matching inner border-glow (box-shadow: inset 0 0 40px rgba(255,255,255,0.1)) that intensifies at the same rate.
  • Layer a second radial with a smaller radius and higher opacity for a &ldquo;hot core + soft halo&rdquo; two-tone spotlight.

Gotchas — read before shipping

  • Throttle mousemove with requestAnimationFrame — updating custom properties on every raw mousemove event can cause paint jank in dense grids.
  • Under prefers-reduced-motion, skip the follow behaviour entirely — either show a static center-anchored glow or omit the effect.
  • The overlay pseudo-element must have pointer-events: none so it doesn't intercept card clicks.
  • Guard with @media (hover: hover) and (pointer: fine) — touch devices don't have a pointer, so the effect adds latency without value.
  • Keep the radial's peak opacity under 0.25 so underlying text stays crisp.
