Interactive preview: https://ui.coderocket.app/docs/blocks/login

## Usage

Get this block from a [saved library export](/docs/export) or the [connected CLI](/docs/agents). The imports below refer to local files installed in your app.

Import `styles/components.css`, then `styles/blocks.css`, then `styles/theme.css` once. Wrap your app in `ThemeScope` from `components/ui/utils` so typography, focus and overlays share the theme. The [installation guide](/docs/export) covers runtime dependencies and React/Next.js setup.

This import is the entry point, not a complete integration example. Supply the required props and connect callbacks to your application. The full ZIP includes `examples/blocks-preview.tsx` with the populated preview and local sample callbacks; adapt those examples to your product.

```tsx
import { LoginBlock } from './components/blocks/auth';

// See Source and props below for the complete typed interface.
```

## Design system

This block consumes your semantic colors, spacing, typography and shape tokens. Import the compiled styles and your theme once as described in [Export](/docs/export).

Icons use Lucide React. Install `lucide-react@1.47.0` alongside React and Base UI.

Dependencies: [Button](/docs/components/button), [Card](/docs/components/card), [Field](/docs/components/field), [Input](/docs/components/input), [Input Group](/docs/components/input-group), [Alert](/docs/components/alert).

## Behavior and accessibility

- Provide meaningful labels for interactive controls.
- Connect action callbacks to your application logic.
- Verify keyboard navigation and contrast in your application.

Status: **experimental** during early access. Sample previews do not send emails, process payments or upload files to a service.

## Source and props

This is the exported source, using the same implementation as the editor. The complete source group is included below; related blocks share it to avoid duplicating behavior.
