## Overview

This is a React dashboard that presents a static, illustrative CI/CD deployment status and a code/build/deployment timeline; it does not implement a CI/CD pipeline or fetch live deployment data. The user-facing flow is browser entry through React into the dashboard, which renders its header, status card, timeline, and footer with fade-in effects. The README separately describes serving a built app with Nginx on EC2. That deployment relationship is documented, but its infrastructure is not implemented in this repository.

Main entry points: [`src/components/Dashboard.tsx`](https://github.com/sagarkakkalasworld/udemy-section1/blob/main/src/components/Dashboard.tsx) (Dashboard), [`src/main.tsx`](https://github.com/sagarkakkalasworld/udemy-section1/blob/main/src/main.tsx) (React entry), [`src/App.tsx`](https://github.com/sagarkakkalasworld/udemy-section1/blob/main/src/App.tsx) (App shell), [`src/index.css`](https://github.com/sagarkakkalasworld/udemy-section1/blob/main/src/index.css) (Global styles)
