Nothing at all when the site serves one language, a dropdown when it serves
several.

## Usage

```vue
<DuxtLocale />
```

## API

No props. Reads `locales`.

## Notes

Built like [`DuxtVersion`](/reference/components/controls/duxt-version) beside it,
so a single-locale consumer never sees that duxt speaks seven languages.

It uses `switchLocalePath` rather than a link to the locale's root: switching
language on a page about deploying should land on that same page in the new
language, not throw the reader back to the front door.
