  First-party open-source JavaScript/TypeScript libraries and tools published by
  Observable to the npm registry under the @observablehq scope (plus the htl
  package). These are client-side visualization, notebook-runtime, and static-site
  build tools rather than REST API client SDKs (Observable does not publish a
  documented public REST API client library). Versions omitted; the npm `latest`
  dist-tag is authoritative.
