## Use it

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

<button class="sds-btn-burst">Button</button>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates an expanding outline and movement and scale (transform). `--sds-duration-slower` controls the speed — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).
