# Crystal Pulse (`.sds-card-crystal-pulse`)

Brightness + contrast + scale pulse — card catches light like a crystal facet. Cards animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

## Use it

```html
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@salkomdesignstudio/sds-motion-forge/dist/categories/cards.min.css" />

<div class="sds-card-crystal-pulse">Card</div>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates filters (blur/brightness) and movement and scale (transform) — compositor-only, so it never causes page reflow. Timing is fixed for this effect, but you can still override animation-duration/timing-function on the element.
