Inspect source tracks, sample rates, channels, durations, and peaks with `ffprobe`.\r\n2. Keep narration intelligible and dominant; duck music roughly 8-12 dB during speech.\r\n3. Add fades, ambience, and effects only when they serve the scene and are license-cleared.\r\n4. Leave headroom, check for clipping, and target platform-appropriate loudness.\r\n5. Render locally with FFmpeg when the files and tools are available, then inspect the final output.\r\n\r\nUse `npx agentbroko video-forge speak` for narration and `--audio` with a short template for a mastered audio track. Never claim a mix was rendered if only a mix plan was produced.\r\n"
