## Overview

This is an Angular pension-management frontend. Users can sign in, then access pension calculation, pensioner records, and transaction history; the pension workflow looks up a pensioner by Aadhaar and submits the resulting pension for processing. The graph distinguishes UI stages, routing/authentication, and API services. The README describes only Angular scaffolding, so product capabilities are inferred from the sampled modules and filenames; unsampled service behavior and component interactions are shown only where evidence supports them.

Main entry points: [`src/app/app.module.ts`](https://github.com/ramkishore417/pension-management-system-frontend/blob/master/src/app/app.module.ts) (App Module), [`src/app/services/login/login.service.ts`](https://github.com/ramkishore417/pension-management-system-frontend/blob/master/src/app/services/login/login.service.ts) (Login and Lists), [`src/app/routing/app-routing.module.ts`](https://github.com/ramkishore417/pension-management-system-frontend/blob/master/src/app/routing/app-routing.module.ts) (Route Table), [`src/app/components/pension/pension.component.ts`](https://github.com/ramkishore417/pension-management-system-frontend/blob/master/src/app/components/pension/pension.component.ts) (Pension Lookup)
