   unrelated nit: I think you can also remove this comment:

   0# Homebrew's python@3.12 is marked as externally managed (PEP 668).
   1# Therefore, `--break-system-packages` is needed.
   

   Since, homebrew has updated the python version number, and the comment isn’t added to any of the other --break-system-packages options where set.
