## Overview

Aman Bank is a console-based account-management application. Users choose menu actions to register customers, open accounts, transact, and inspect account history, estimates, or statistics. Main is the interaction orchestrator; BankService manages in-memory customer/account collections and account lookup, creation, and transfers, while account models enforce transaction rules and create transaction records. The README documents these capabilities; the sampled source shows their main call paths. The account-type enum is represented from the tree and README, but its source was not sampled.
