Good lord. This reeks of LLM... why should I use your product when you can't be bothered to have a human write it? Why should I trust it to work correctly or have been decently tested, neither of which is a given when having an AI vibe-code it?

And why is it one huge single page of word salad instead of self-contained units?

Anyway, good to see someone post a fully self contained example demonstrating core concepts. At least one thing done right.
