# Prism Edge (`.sds-btn-prism-edge`)

A spectral border cycles hue while sweeping emphasis around the frame. Buttons animation in SDS Motion Forge v5.0.0. It loops continuously as soon as the class is applied.

- Animated properties: clip-path, filter, opacity
- Compositor-only: yes
- Needs child elements: no
- Needs per-character spans: no
- JavaScript: none required

## 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-prism-edge">Button</button>
```

## How it works

Plays as soon as the class is applied, looping continuously. It animates a clip-path mask, filters (blur/brightness) and opacity — compositor-only, so it never causes page reflow. `--sds-duration-dramatic` controls the speed — override either on the element or :root (the sds-fast/sds-slow modifier classes do exactly that).
