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

Page footer (`.kwac-footer`): hairline on top, centered wordmark, one muted
sentence and an optional listing token line (`.kwac-token`). Last child of `Page`.

## Props

```ts
interface FooterProps {
  /** Brand wordmark, defaults to "Kupp-west". */
  brand?: string;
  /** One short muted sentence under the wordmark. */
  children?: React.ReactNode;
  /** Optional technical listing token rendered in tiny light-gray type, e.g. "[kwkw-131282-153195-kwkw]". */
  token?: string;
}
```
