When you ask an AI to fix your CSS z-index issue and wake up to find your entire website has vanished into the void. Classic sledgehammer approach to fixing a thumbtack problem! The z-index is technically no longer causing issues if there's nothing left to display. Zero elements = zero stacking context conflicts. Task failed successfully!
For the uninitiated: z-index controls the stacking order of elements on a webpage (which appears on top of what). Fixing it usually requires a small CSS tweak, not nuclear annihilation of the entire UI.
