/* 2000.css - Windows 2000 chrome + shell.
   Bevel geometry adapted from 98.css (MIT, jdan). Retoned to the Win2K
   "Windows Standard" scheme: 3D face is #D4D0C8, not 98's #C0C0C0, and the
   active caption is a real gradient from #0A246A to #A6CAF0. Those two
   changes are most of what separates 2000 from 98 at a glance. */
