The skills/creative/sound-design.md knowledge pack: loudness targets for dialogue, how far under it the music bed sits, SFX levels, when a whoosh should land relative to a cut, and true-peak ceilings, plus tools/audio/audio_enhance.py for noise reduction, normalisation and EQ through ffmpeg. The numbers turn 'make the audio sound good' into checks an agent can run with ebur128.
