Don't Touch If It Works

You know that one piece of code written by someone who left the company 5 years ago? The one with no comments, nested ternaries, and a variable named "temp2_final_ACTUAL"? Yeah, that's your load-bearing duct tape right there. Sure, it violates every principle in Clean Code, but production's been humming along just fine. Touch it and suddenly everything breaks in ways you didn't even know were possible. It's like Jenga, except the blocks are held together by prayers and Stack Overflow answers from 2012. The golden rule of legacy code: if it ain't broke, for the love of Linus, don't refactor it.
