Resolve Audio / Fairlight

Thin router; depth stays in the kernel.

• Live tool mechanics — docs/kernels/audio-fairlight-kernel.md (the timeline audio/Fairlight boundary).
• Offline planning + bus routing — resolve-advanced/README.md → audio_plan, fairlight, audio.

Rough mix before anything else

If the ask is "make this sound balanced" rather than "route these buses", start with media_analysis mix_plan (Python server, no Resolve needed). Give it the dialogue stems and it derives the dialogue-normalisation gain, the music-bed level under it, and ducking windows from the dialogue's own silence — then renders a premix and measures it, so what you report is the loudness achieved rather than the gain arithmetic.
