This seems more minimal than demanding installation of https://docs.overturemaps.org/getting-data/overturemaps-py/ or another custom tool?

I think adding such a script is a good idea. I get the following error:

Downloading release 2026-02-18.0: 7.408446,43.722901,7.4405,43.752481 to data/sources/monaco.parquet
HTTP Error:

I am not good at reading bash. I would prefer if we could hard-code the Overture release and the bounding box in the SQL. In the current state I would need to ask a chatbot or read about bash's syntax to know how to use this script.
