That’s what I humanized using AI, OK, I’m using Google Translate, I’m not very good at English.

Fair point, tbh. Putting everything in one file, plus the AI assisted development, has left me with code that’s hard to read and maintain. Some parts still use minified style names, and that’s on me. I went with a single file so people could download it and run it offline, no build step and no dependencies. fwiw, that’s a reason, not an excuse for code that’s hard to follow. What I still need to do is split it into clearer modules, rename things properly, and document where the original, adapted, and third-party code begin and end. If you have specific suggestions for making it easier to debug or contribute to, lmk.
