KnotzerIO/find-the-impostor ? reverse-engineered prompt

Build me a local first party game app where a group of 3 to 10 people can play “find the impostor” on their phones. The host should be able to set player names, pick a word category or add a custom one, choose how many impostors there are, and optionally turn on hints. Then each player takes a private turn to see either the secret word or, if they are an impostor, a clue that helps them blend in. After that, the app should guide the group through a couple of short discussion rounds, let everyone vote, and then reveal who won.

Make it feel polished and easy to use, with a clean mobile friendly interface, installable as a PWA, and able to work offline with game data saved locally. Keep it multilingual in English and German, and use current Next.js docs if you need to check anything.
