  String's sandbox/test environment. Every organization gains access to the
  sandbox on creation, where it can create API keys, register games and smart
  contracts, and test the integration before upgrading to production. String
  does not publish magic test card numbers or fixed test tokens in its public
  docs, so none are recorded here (no fabrication) — the test surface is the
  sandbox dashboard and sandbox-issued keys.
