description: 'First-party Coin Railz client packages. Every npm and PyPI package is published by the single maintainer
  tdnupe3 (GitHub: T. Kellogg, company ''Coin Railz'', blog https://coinrailz.com; llms.txt names the operator as
  Kellogg Holdings LLC), so official: true throughout. NOTE ON SOURCE LINKS: the repository URLs declared in the
  npm/PyPI metadata point at github.com/coinrailz/*, and that GitHub organisation does not exist (404 on github.com/coinrailz
  and api.github.com/orgs/coinrailz); the actual code lives under https://github.com/tdnupe3/. Declared URLs are
  kept in `declared_repository` and the reachable one in `source`.'
