## Overview

This is a browser-based banking application backed by a Java API. Users sign up or log in, then check balances, deposit, withdraw, transfer funds, and review transactions; password-reset and administrator workflows are separate capabilities. The frontend excerpts show which API routes the screens call. Backend internals are represented by their named modules, but their call wiring is not asserted because those sources were not sampled.

Main entry points: [`frontend/auth.js`](https://github.com/anki-0015/bankingmanagementsysteme/blob/main/frontend/auth.js) (Sign-in and reset), [`frontend/dashboard.js`](https://github.com/anki-0015/bankingmanagementsysteme/blob/main/frontend/dashboard.js) (Account dashboard), [`frontend/transactions.js`](https://github.com/anki-0015/bankingmanagementsysteme/blob/main/frontend/transactions.js) (Transaction history), [`backend/src/main/java/com/example/banking/controller/AccountController.java`](https://github.com/anki-0015/bankingmanagementsysteme/blob/main/backend/src/main/java/com/example/banking/controller/AccountController.java) (Account routes)
