Credits go to @kmh for creating this style. It comes in both a light and dark version (check the links for usage instructions).
If you don't want to fiddle with code and stuff, loma.ml has already installed it server-wide, and should be available straight away for new accounts (If not, go to Settings>Display>General Theme Settings and change it from there. Or follow the guide in any of the links above).
