Give feature/pricing cards a premium feel: a soft radial spotlight follows the cursor across the card and lifts its border. Keep the glow subtle and low-contrast. Falls back to a plain static border under prefers-reduced-motion and on touch. Do not use on text-dense reading surfaces.

spotlight-card

A radial spotlight that follows the cursor across a card. Part of motion-anything; obeys MOTION-SPEC.md. Technique popularized by Aceternity UI, reimplemented dependency-free.

When to use it

Feature cards, pricing tiles, or a card grid where one should light up under the pointer.

When NOT to use it (restraint)

Text-dense reading surfaces — the glow distracts. Keep it low-contrast and subtle.
Touch-only contexts — there is no cursor; it falls back to a static border automatically.

How to apply

Copy spotlight-card.css and spotlight-card.js into the project, and link them.
Mark the card:

html <div class="spotlight"> … </div>

Auto-attaches to .spotlight. JS writes --mx/--my; the CSS paints the glow there.

Accessibility & performance

Disabled under prefers-reduced-motion and on (hover: none) touch devices (static border stays).
Paints a radial-gradient only — no layout thrash.

Framework notes

React: call attachSpotlight(ref.current) in useEffect, guarded by the same checks.
