## 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 { DatePicker } from '@app/components/ui/date-picker.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><DatePicker label="Delivery date" defaultMonth="2026-11-01" /></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/dialog-modal/)

- Calendar embedded in package-owned native modal Dialog; uses existing focus, Escape and return behavior.
- Browser-forced dismissal can supersede a rejected close request; applications should normally accept native close requests.
- ISO value collection and open state can each be controlled. A named hidden input submits dates joined by /. Open data-state is derived; hydrate in an island.

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