Inference script for Zeta Chroma

I couldn't find any guidance on how to run lodestones Work-in-progress Zeta-Chroma model. The HF repo just states you can use the model as is in comfyui and there is a conversion script for ComfyUI as well in the repo. I don't have ComfyUI, so I made Claude Opus 4.6 write an inference script using diffusers. And by black magic, it works - it wrote like 1k lines of python and spent an hour or so on it. I don't know what settings are best, I don't know if anybody knows what settings are best.
