# ffmpeg: the Worker transcodes audio to .m4a. yt-dlp: downloads YouTube audio.
# yt-dlp is installed via pip in a venv rather than the standalone PyInstaller
# binary: the binary adds a ~1s unpack cost per invocation and extracts slower,
# so pip roughly halves resolution latency. deno solves nsig challenges.
