Regex Programming Email Parsing

Someone really woke up and chose CHAOS by creating a regex pattern that accepts basically every Unicode character known to humanity in email addresses. Like, sure, let's just throw in every accent, diacritic, and symbol from every language ever invented because why not? The absolute AUDACITY of suggesting we register a 2-character domain with "a couple of these badboys" to see which websites break is honestly chef's kiss level chaos engineering. This is basically the email validation equivalent of "I'm not stuck in traffic, I AM the traffic." Instead of writing reasonable regex for email validation, someone decided to stress-test the entire internet's email parsing systems by exploiting the fact that technically, according to specs, emails can contain way more characters than most developers think. It's like finding out your calm, predictable friend is secretly an agent of anarchy.
