Generic action primitive using semantic theme classes.

[All components](https://rickylabs.github.io/netscript/design-system/components/) · [Theme builder](https://rickylabs.github.io/netscript/create/) · [Implementation source](https://github.com/rickylabs/netscript/blob/main/packages/fresh-ui/registry/components/ui/button.tsx)

## Live preview

## Install

```bash
netscript ui:add button
```

## Usage and examples

The preview runs this JSX with the installed components. Import any composed primitives from your UI directory.

```tsx
import { useState } from 'preact/hooks';
import { Button } from '@app/components/ui/button.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><div class="demo-row"><Button onClick={() => report("Changes saved")}>Save changes</Button><Button variant="outline">Cancel</Button><Button disabled>Disabled</Button></div></div><p role="status">{notice}</p></>);
}
```

## Props

Generated from native `deno doc --json --private` over the shipped implementation. Compound component props retain their owning interface; native attributes pass through where declared.

## Contract and compatibility

Accessibility pattern: [WAI-ARIA guidance](https://www.w3.org/WAI/ARIA/apg/patterns/button/)

- Native DOM attributes pass through where the implementation accepts them.

Design contract values marked planned are not implementation props. The props above describe what ships today.
