## Overview

UNIQUE Bank is a React frontend demo, not a real banking service: signup and login are client-side, and account activity uses fictional data with browser-local persistence. The user journey runs from signup/login into a routed dashboard, then branches into account management, banking services, plans, and lifestyle offers. Dashboard and domain views consume shared banking state; the sampled context persists selected values in localStorage. The graph reflects documented capabilities and indexed imports, but unsampled modules and their internal calls are not verified.

Main entry points: [`src/context/BankingContext.jsx`](https://github.com/yashaswinimullalli/banking-system/blob/main/src/context/BankingContext.jsx) (Banking state), [`src/pages/DashboardPage.jsx`](https://github.com/yashaswinimullalli/banking-system/blob/main/src/pages/DashboardPage.jsx) (Dashboard page), [`src/App.jsx`](https://github.com/yashaswinimullalli/banking-system/blob/main/src/App.jsx) (Route application), [`src/components/dashboard/Header.jsx`](https://github.com/yashaswinimullalli/banking-system/blob/main/src/components/dashboard/Header.jsx) (Navigation header)
