Thank you, timeout is new to me and helpful. And MaiZure! Ye gods. That website is an absolute gold mine for improving techniques around reading and understanding source code.

I was curious as well. According to the author, "All the diagrams were hand-crafted in PowerPoint."

You can do those flow diagrams easily with Mermaid.
