I just want to say that despite the AI negativity in other places, this highlights the positive aspect of it. I'm sure this could have been done without it, but I'm glad OP could get it out faster for a low-risk use case, shared it with us, and in the process taught a little bit of refining to others. It's a fun minigame.

Thank you, almost like you read my manifest for this haha. I was concerned the learning would get overshadowed by the LLM use. Hope you learned some interesting facts that help you understand the why of refining a little bit more. I started developing this before the conversation around oil became mainstream media again.
