Shame.css
Pedantry: can we call it "guilt.css" instead?  In psychological literature, guilt is defined as the "I did something bad" emotion, shame is the "I am bad" emotion.  The crucial difference between them is that guilt can be fixed by making amends.  That seems like exactly the mindset you want to encourage with this: guilt.css implies that you feel guilty about all the hacks you have and want to make amends, while shame.css implies that your codebase is a steaming pile of shit.
