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

Light-gray rounded card (`.kwac-detail-card`, white on `alt` bands) that
presents one component of the kit: image on a white inset, uppercase kicker,
bold title and muted copy. Child of `DetailGrid`.

## Props

```ts
interface DetailCardProps {
  /** Product image, shown 4:3 contained on a white inset with 14px radius. */

  /** Tiny uppercase manufacturer line above the title, e.g. "Auto Hak". */
