Dharun-Vengatesan/smart-stadium-experience ? reverse-engineered prompt

Build me a smart stadium experience app that helps fans get around a busy venue in real time.

I want a polished dark mode frontend with a premium feel, smooth responsive navigation, and offline fallback so it still works if the live data drops. The app should show crowd levels, estimated wait times, and a simple route comparison so users can see the better path to their gate, food, or restroom. Make it feel accessibility first, clear and easy to use on a phone.

Also set up a small backend that serves a basic status check and a live queue endpoint with mock real time telemetry and AI style insights. If the live service is unavailable, the app should switch to a sensor unavailable state and show cached simulation data instead of breaking.

Use a clean modern React setup for the frontend and a lightweight Node server for the backend. If you need current setup details, check the latest docs online and keep it simple.
