/* ================================================================
   MAC.CSS — Mac OS 9 "Platinum", done properly.

   Reference points, from the real thing: the default desktop is the
   blue-lavender woven pattern, not gray; the menu bar and titlebars
   share the same fine horizontal pinstripe; an INACTIVE window hides
   its widgets entirely and drops to plain platinum; the highlight
   colour is Platinum blue; scroll thumbs are the lavender pill with
   grip lines; buttons are rounded platinum with a gradient, and the
   default button wears the heavy return ring. No hover tints on the
   title boxes — that is OS X talking.
   ================================================================ */
