Looks like you are not really familiar with how Tailwind works. And if you don't understand it of course Vite or a build step will look weird. But I suggest first getting familiar with the thing you are discussing to avoid adding misguided comments to the discussion that really don't add any value.
Though you are of course correct, I see no problem with somebody reading about technologies that they themselves don't use here on HN. I personally read HN to get familiar with new technologies that I may find useful in my work and private life. I first heard of OpenAI and Anthropic here.
