Jordan-Batu/cie-campus-camp ? reverse-engineered prompt

Build me a simple mobile friendly campus camp web app called CIE Campus Camp.

I want a clean landing page that feels like a small event or info site, with a nice layout, clear sections, and a polished look on phone and desktop. Include basic navigation, some useful campus camp content like an overview, schedule or highlights, and a way to show important updates or contact details. Make it work well offline too, since this looks like a small progressive web app. Add the app manifest and service worker so it can install like an app on a phone.

Keep it lightweight and easy to use, with everything working from the main page. If you need to check current best practices for the offline setup or install prompt, feel free to look up the latest docs online.
