summary: >-
  HM Land Registry ships no embeddable API widget — there is no hosted checkout,
  no drop-in title search box and no embedded dashboard for consumers of its APIs.
  What it does publish, and publishes properly, is a government design system: a
  front-end style library, a React component library built on the GOV.UK Design
  System, Jinja and WTForms macro packages for Python services, and a prototype
  kit. These are the components HMLR's own service teams (and, since they are
  public on npm and GitHub, anyone building an HMLR-adjacent service) assemble
  user interfaces from. They are recorded here because they are genuine
  first-party client-side component libraries, and kept distinct from the SDK
  question: none of them talks to an HMLR API.
