Can't Forget That DOCTYPE Declaration

The AUDACITY of web developers just slapping !DOCTYPE html at the top of every file like some magical incantation! 💅 Honey, we're all just copying and pasting that declaration like it's a secret recipe ingredient. Does anyone ACTUALLY know what it does? It's basically the web development equivalent of adding salt to your soup - you're not sure how much you need, but you know everything breaks without it! The browser's like "tell me what language you're speaking or I'll have a TOTAL meltdown," and we're like "fine, take your DOCTYPE, you dramatic little rendering engine!" 🙄
