Everything is fun until about 10k-20k lines of code. The problem is that those lines are a grey box. You can see the code, but you can't navigate around in it. You are stuck stumbling around, trying to figure out how it works, so that you can take it from there. The temptation to just throw it in the garbage and start over, by hand, is high.

All pages are responsive until you add CSS. LLM wants to force it.
