// Steamify Vapor (Steamify GNOME theme). Its stylesheet.css, which GNOME Shell loads
// by itself, is the SteamOS look. This code: GNOME opens the overview after login;
// Ubuntu starts on the desktop. So does this: the overview stays closed while the
// shell starts up, and is available again right after.
