The failure here was ruff detecting some things in the Jupyter notebooks that needed fixing up. This includes:

• Unused imports (which could be automatically applied).
• Comparisons of booleans (e.g., just needing if <boolean> rather than if <boolean> == True).
• An undeclared variable (that has never been gotten to, yet).
• Some imports needing to be at the top of a cell.

I let pre-commit take care of the unused imports and then manually applied the fixes for the other three points. I've run all affected notebooks against UAT, but would feel more comfortable if someone else also did the same.

Oh - I just realised I also need to bump some image versions. Will do that now.

These checks all look good and each updated notebook has an associated minor version change. 🚀
