  The SVB developer portal provides a testing surface for its commercial banking
  APIs: a sandbox environment and an interactive OAuth playground for exercising
  the client-credentials token flow, alongside downloadable Postman/Insomnia
  request collections. Specific test values (test account numbers, test card
  numbers, simulated payment states) are published inside the partner-gated docs
  and were not captured verbatim to avoid fabrication — the tooling below is what
  the public portal advertises.
sandbox:
  environment: true
  oauth_playground: true            # interactive token-flow console on the portal
  separation: partner-registered sandbox credentials distinct from production keys
  collections:
    - type: postman
      note: Portal-published Postman request collection for the commercial banking APIs.
    - type: insomnia
      note: Portal-published Insomnia request collection.
  test_values: partner-gated        # published inside authenticated docs; not captured (no fabrication)
