/*
  Register the USD reference rate in the multi-currency module (sandbox only).

  Enabling the module is not enough: an invoice can only carry a currency that
  exists in the module's rate table, otherwise Dolibarr silently falls back to
  EUR (observed: POST /invoices with multicurrency_code=USD returned EUR).

  The rate is the ECB EUR/USD reference of the day the invoice is settled —
  per the KM amendment, art. 2/4. It is written here so the invoice carries the
  contractual obligation ($2,500 / $3,000) rather than a drifting EUR value.
  The invoice then carries the obligation itself, not a counter-value.

  Run:
    DOLIBARR_ADDRESS=https://erp-sandbox.arcodange.lab \
      deno run -A test/sandboxCurrencySetup.ts --code USD --rate 1.14416
