Built from the DJ side of the problem rather than the developer side. Fans scan a QR code, send a request over Telegram with nothing to install, and watch it climb a live board on the screen behind the booth. The queue ranks by votes so the floor decides what comes next, duplicate requests collapse into one, and every set quietly assembles itself into a Spotify playlist of what actually got played — which followers can pick up afterwards. A dashboard covers requests submitted, people in the room, and voting activity. It replaces shouting over the monitors and scraps of paper on the mixer.
