- script.js: Clean up initSocket() to remove dead listener mode detection logic.
- index.html: Remove dead #listener-mode div (now served by listener.html).
- server.py: Move 'abort' import to top-level Flask import instead of per-request import.
- techdj_qt.py: Fix StreamingWorker to create fresh socketio.Client on each streaming session, preventing stale socket state on reconnect.
- techdj_qt.py: Fix time.sleep(0.2) blocking GUI thread in stop_streaming() by removing it and using try/except for clean disconnect.

dj_panel_password, secret_key, music_folder, stream_bitrate, max_upload_mb,
cors_origins, debug (copy to config.json to use)
