Document API endpoint missing cdn

High Severity

patchStarterConfig sets documentAPIEndpoint to https://${repositoryId}.${host}/api/v2, but Prismic’s Content API uses the cdn subdomain (for example https://my-repo.cdn.prismic.io/api/v2). The downloaded starter’s config is overwritten with a host that matches the builder URL pattern, not the Document API, so the project may fail to fetch content after download.
