## Install

```bash
netscript ui:add card
```

## 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';
import { Card } from '@app/components/ui/card.tsx';
import { Input } from '@app/components/ui/input.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><Card><Card.Header><Card.Title>Order SO–10480</Card.Title><Card.Description>Review fulfillment details</Card.Description></Card.Header><Card.Body><Input aria-label="Tracking number" placeholder="Tracking number" /></Card.Body><Card.Footer><Button onClick={() => report("Order saved")}>Save changes</Button></Card.Footer></Card></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.

| Owner | Prop | Type | Optional | Description |
| --- | --- | --- | --- | --- |
| `CardSectionProps` | `children` | `Renderable` | No |  |
| `CardSectionProps` | `class` | `string` | Yes |  |
| `CardSectionProps` | `data-part` | `string` | Yes |  |
| `CardSectionProps` | `data-scope` | `string` | Yes |  |
| `CardProps` | `interactive` | `boolean` | Yes |  |
| `CardProps` | `variant` | `"default" \| "rule"` | Yes |  |
| `CardProps` | `size` | `"md" \| "sm"` | Yes |  |
| `CardProps` | `state` | `"rest" \| "hover" \| "focus" \| "selected"` | Yes | Visual snapshot; native child controls remain the keyboard targets. |
| `CardTextProps` | `data-scope` | `string` | Yes |  |
| `CardTextProps` | `children` | `Renderable` | No |  |
| `CardTextProps` | `class` | `string` | Yes |  |

```typescript
CardSectionProps extends Omit<JSX.HTMLAttributes<HTMLDivElement>, "class" | "children">
CardProps extends CardSectionProps
CardTextProps extends Omit<JSX.HTMLAttributes<HTMLParagraphElement>, "class" | "children">
```

## Keyboard

| Key | Action |
| --- | --- |
| `Tab/Shift+Tab` | Focus native child actions; the card container adds no keyboard target |

## Contract and compatibility

Accessibility pattern: noninteractive presentation

- Native DOM attributes pass through where the implementation accepts them.
- Header/body/footer presence comes from namespace composition, not phantom boolean root props. Rule has only a top border, with no resting fill/radius/shadow.

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