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

Call-to-action pill. Renders an `<a>` with the semantic class `kwac-button`
(or `kwac-cta` when compact). Use `primary` for the one main action of a
section and `ghost` for the secondary one; place both inside `CtaActions`
or at the bottom of an `OfferCard`.

## Props
