  Replica ships no client SDK, because it publishes no public developer API. The packages below are
  first-party open-source libraries published by the Replica GitHub organization (several inherited
  from the Sidewalk Labs project the company was spun out of). They are modelling/data-tooling
  libraries, NOT API client libraries - no `SDKs` pointer is wired in apis.yml for that reason.
