 * Everything here applies only when <html data-theme="classic">: grey
 * bevelled windows with blue title bars on a teal desktop, a black
 * console window for the terminal, and a taskbar at the bottom.
 *
 * The 3D edges are all box-shadows: a light line on the top/left and a
 * dark one on the bottom/right make a surface stand out ("raised");
 * swapping them makes it look pressed in ("sunken").
