# --- HF Space (Docker SDK) - MicroMixer-2 Discord demo
# Pinning anything to old versions is the wrong move on Python 3.13:
# the stdlib `audioop` is gone and huggingface_hub dropped HfFolder.
# We use the latest of everything instead, and keep audioop-lts in
# the dep list because Gradio's pydub import still needs `audioop`.
