Only God Knows What This Code Does Now

Coding something and understanding it for exactly 2.7 seconds before it becomes an indecipherable mess? That's the universal developer experience. You write some brilliant hack at 2AM, feeling like a genius, only to return later wondering if your cat actually wrote it while walking across your keyboard. The worst part? That code somehow runs perfectly in production, and you're now terrified to touch it because it's held together by digital duct tape and prayers. Documentation? That would've been a great idea... yesterday.
