      Chi is consumed in production by Lumen's own properties: developer.lumen.com,
      docs.lumen.com and www.lumen.com all carry class="chi" on the root element and
      preconnect to lib.lumen.com. @centurylink/chi-vue is loaded as a module-federation
      shared dependency by the Developer Center SPA but is not published to npm.
gaps:
  - >-
    No embeddable API-facing component (no hosted checkout, ordering widget, embedded
    dashboard or prebuilt console surface) is published. Chi is a presentation-layer
    design system, not an API integration surface.
