Abanoub-Git/MysteryMe ? reverse-engineered prompt

Build me a polished little web app called MysteryMe that feels playful and mysterious, with a clean landing page and a simple interactive experience for the user.

I want it to run nicely in the browser, look good on desktop and mobile, and make the whole thing feel fun right away. The main flow should be easy to follow, with a clear start, some kind of guessing or reveal moment, and smooth feedback as the user interacts with it. Keep the design modern and a little suspenseful, but still simple and easy to use.

Please set up whatever is needed in the existing project structure and make the app feel finished, not like a demo. If you need current docs or a small helper library, look up the latest info online first.
