## Overview

This is a Spring Boot REST banking application. A client calls the account API; documented capabilities cover account creation, retrieval, deposits, withdrawals, listing, deletion, transaction history, and monthly interest. The README describes a layered design with DTO mapping, services, JPA repositories, and configurable persistence. Source excerpts were not provided, so implementation-level call directions—especially for transactions and interest—cannot be verified; those links are marked as unverified rather than presented as observed calls.
