kashmir-xtha/spot-the-imposter ? reverse-engineered prompt

Build me a polished offline party game app called Find the Imposter.

I want a React Native app with Expo and TypeScript where people pass one phone around, each player taps to privately reveal their role, and most players see a secret word while the imposter only sees the category hint. The app should let me set up the game with a player count from 3 to 20, choose categories, and pick how many imposters there are. It should feel smooth and clear, with a discussion screen and an optional countdown timer, plus a results screen that shows who the imposters were, what the secret word was, and a full breakdown for each player.

Please make it fully self contained and work without any backend or internet connection. Re randomize avatars and game setup each round, and make sure the previous player’s info is cleared before the next turn so nothing gets leaked. If you need current Expo or React Native details, look up the latest docs online.
