Mafia-Hands/Mafia ? reverse-engineered prompt

Build me a polished online multiplayer Mafia game where people can join a room, get assigned to civilians or mafia, and play through a full match with voting and elimination until one side wins.

I want a smooth frontend and backend setup that works locally, with real time multiplayer updates so players see the game state change live. Make it easy to start both sides, and make sure the app is wired for a local server during development. The experience should feel like a simple party game people can open in a browser and play with friends.

Keep the rules close to the classic Mafia format, but it’s okay if the game logic is flexible enough to support future tweaks. If anything is unclear, check the project docs or look up current docs online if you need to.
