# Live balances per bank account, plus a Dolibarr cross-check by fk_account.
#
# Usage:
#   bank-balance.sh
#
# Outputs each bank account (Qonto + Wise) with:
#   - current live balance (from each bank's API)
#   - sum of all Dolibarr payments touching it (per fk_account)
#
# The sum-of-payments isn't the bank balance — it's just the cumulative
# operations Dolibarr has recorded on that account. Useful as a sanity check
# (e.g. "did I record everything?"). The bank-side current balance is
# authoritative.
