io structure & polish

I am fully capable of polishing the user interface. I could make some wait times, pretty ASCII boxes and dividers, better method of asking questions and collecting responses, et al. I don't think I'll do this on account of knowing there are some deeper back-end programming issues that need to be addressed. Coding on top of those before fixing the deeper issues just makes more work. It's bad form.

The issue does not name files, tests, or entry points. First locate the program's input and output flow, then clarify which UI improvements are in scope and how they should be evaluated. Done would require an agreed set of wait-time handling, ASCII formatting, and question-and-response changes.
