qupagaming-pixel/Khelgalli3.0 ? reverse-engineered prompt

Build me a TypeScript web app for Khelgalli3.0 that feels like a polished modern site and is ready to deploy.

I want a working frontend with a simple home experience, a clean layout, and a few core screens that make sense for a small app or game style platform. If Firebase is already part of the setup, connect the app to it for data storage and basic backend features, and make sure the Firestore and storage rules are set up safely. Use the existing project structure and keep everything running smoothly in development and production.

Please make it look good on desktop and mobile, handle loading and error states nicely, and include any basic config or environment setup needed so I can run it locally and deploy it without a lot of manual fixing. If you need current docs or best practices for the tools in this repo, look them up online and use them.
