## Usage

Get this component 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/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.

```tsx
import { Alert } from './components/ui/alert';

<Alert title="Everything is up to date." variant="success">Your changes have been saved.</Alert>
```

## Design system

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

## 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.

```tsx
"use client";
import type { HTMLAttributes, ReactNode } from "react";
import { cx } from "./utils";
export function Alert({
  title,
  variant = "info",
  announce = false,
  role,
  children,
  className,
  ...props
}: Omit<HTMLAttributes<HTMLDivElement>, "title"> & {
  title?: ReactNode;
  variant?: "info" | "success" | "warning" | "destructive";
  announce?: boolean;
}) {
  return (
    <div
      {...props}
      role={role ?? (announce ? "alert" : undefined)}
      className={cx("cr-alert", className)}
      data-variant={variant}
    >
      {title && <strong>{title}</strong>}
      {children && <div>{children}</div>}
    </div>
  );
}
```
