  Rain provides a sandbox / test environment for partners. Per Rain's developer
  materials, on request Rain provisions a sandbox environment where engineers can
  test end-to-end flows (card issuance, flow of funds, balances, controls,
  webhooks) without touching real funds. Access is granted through onboarding /
  compliance review; specific test card numbers, test tokens, and fixture values
  are published only inside the access-code-gated developer docs and are therefore
  not reproduced here (no fabrication).
sandbox:
  available: true
  provisioning: on-request via onboarding
  test_vs_live: separate sandbox environment; no live funds
  published_test_values: none (gated)
