## Overview

This is a small demo login experience: the browser renders a sign-in form, checks hard-coded demo credentials, stores a signed-in flag, and renders a welcome view. The sampled JavaScript shows these behaviors and their localStorage interactions; HTML contents were not sampled, so page wiring is not asserted. main.py is a separate greeting script with no shown connection to the web flow.

Main entry points: [`app.js`](https://github.com/chaitanyakonduri282007/first-repo/blob/main/app.js) (Login handler)
