  Volt provides a full sandbox environment separated from production by host.
  Credentials (Client ID/Secret + API username/password) are self-issued in
  Fuzebox. No fixed magic test card/IBAN numbers are published verbatim in the
  fetchable spec; the Accounts sandbox instead exposes explicit simulation
  endpoints to drive incoming-payment events. Never invent test values.
