PR summary

Caution

🚨 DO NOT MERGE 🚨

This is not a real PR, it is designed to allow me to run various experiences on the macOS 26 CI runners. Hopefully, I can figure out a way to make them faster.

AI Disclosure

I gave the following prompt to AI:

disable all actions except for python 3.14 on macos-26. Make do_not_merge always fail as an additional warning.

I then added comments and added a step to tests.yml to give me the size of "/opt" after Homebrew installs packages.

PR quality check

  • Use an expressive title, e.g. "Fix title font property precedence"
  • [/] New and changed code is tested
  • [/] Plotting related features are demonstrated in an example
  • [/] New features and API changes have release notes
  • [/] Documentation complies with general and docstring guidelines

Sorry, something went wrong.

Uh oh!

Comment out git describe

I assume that we are using this for some type of side-effect to validate that the repository is good? `git describe` simply prints out a human readable description of HEAD.
