Stream Spectator lets players choose when others can watch them in-game. A streamer enables access with /stream, and viewers join with /spectate <player>, which teleports them to the target and switches them to spectator mode. The streamer is notified when someone starts watching. Viewers can use /leave to return to their previous location and game mode, while /endstream or the streamer's disconnect ends access and returns all viewers.
