I am a bit frustrated that I don't have a great "tool" environment to build out this stuff, because of having to futz with the I/O. Like most of that stuff is "well I know how to write the Python to do the last step, but wrapping it all up in a simple web UI is Too Much Work". That effort might be small, but it's still orders of magnitude larger than the snippet!

Lots of TUI interfaces try to approximate this, but I think I really just need to build out something a bit like https://anvil.works/
