“Gilded Rose” refactoring kata in Ruby — as if it is 2024

Recently, I didn’t have time or resource for serious writing. I had plans for several long articles for the summer that gone, but unfortunately not many have came of that. But last night I have stumbled upon famous (so it seems, though I have never seen it before) refactoring kata, and had an impulse for trying my hands on that, writing down some thoughts on my ways of writing code along the way.
