# usePageMeta

Sets the page `<title>` and/or `<meta name="description">` while a component is mounted, then restores the previous values on unmount.

## Signature

```ts
function usePageMeta(params: UsePageMetaParams): void;

interface UsePageMetaParams {
  title?: string;
  description?: string;
}
```

| Param         | Type     | Description                                 |
| ------------- | -------- | ------------------------------------------- |
| `title`       | `string` | Value to set as `document.title`            |
| `description` | `string` | Value to set in `<meta name="description">` |

Both params are optional — pass only the ones you need.

## Usage

```tsx
function ArticlePage({ article }: { article: Article }) {
  usePageMeta({
    title: article.title,
    description: article.summary,
  });

  return <main>{article.content}</main>;
}
```

```tsx
// Title only
function DashboardPage() {
  usePageMeta({ title: 'Dashboard' });
  return <div />;
}
```

## Notes

- Restores the previous `document.title` and `<meta>` content when the component unmounts, so nested or sequential usage is safe.
- If no `<meta name="description">` tag exists in the document, one is created and removed on cleanup.
- Client-only (`'use client'`). Does not run during SSR.
