How mario-cartoon/bank-service works

Bank API — a Go REST banking service. The main workflow runs from HTTP routes through authentication middleware and handlers into domain services, which apply account, card, credit, and analytics rules and use PostgreSQL repositories for persistence. Credit creation can consult the Central Bank rate; a background scheduler asks the credit service to process overdue payments. README capabilities such as forecasting and SMTP are retained, though SMTP use is not visible in sampled service code. Edges reflect excerpts or README statements; uncertain links are omitted.
