GalleryItem from @kuppwest/apple-clean. Use via `window.KuppwestAppleClean.GalleryItem` (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).

White rounded tile (`.kwac-gallery-item`, 22px radius, 26px padding) with a
square, contained product image and a muted caption. Child of `Gallery`.

## Props

```ts
interface GalleryItemProps {
  src: string;
  alt: string;
  /** Small muted caption under the square image. */
  caption?: string;
}
```
