You spend three days wrestling with a build error that makes absolutely no sense. You've tried everything—cleared cache, deleted node_modules, sacrificed a rubber duck to the debugging gods. Then one morning you wake up, run the build command, and it just... works. No code changes. No updates. Nothing. The sheer terror of not knowing what fixed it is somehow worse than the bug itself. Did it fix itself? Was it a cosmic ray? A race condition that finally lost the race? You'll never know, and that uncertainty will haunt you forever. Because if you don't know what fixed it, it can come back at any moment. Sleep tight.
