# useViewportKind

`useViewportKind()` returns simple responsive flags used by OpenPencil editor UI.

Use it when your shell needs a light abstraction over breakpoints instead of wiring `useBreakpoints()` directly.

## Usage

```ts
import { useViewportKind } from '@open-pencil/vue'

const { isMobile, isDesktop } = useViewportKind()
```

## Returns

- `isMobile`
- `isDesktop`
