IncludedItem from @kuppwest/apple-clean. Use via `window.KuppwestAppleClean.IncludedItem` (bundle loaded from the root `_ds_bundle.js`). Wrap the tree in `<Page>` (full provider chain in README.md — components read theme/i18n from that context).

Small white rounded tile (`.kwac-included-item`, 18px radius) with a bold
title and one muted line. Child of `IncludedGrid`.

## Props

```ts
interface IncludedItemProps {
  /** Bold 15px title, e.g. "Montagematerial". */
  title: string;
  /** One short muted line. */
  children: React.ReactNode;
}
```
