/* ===========================================================================
   Nezha monitoring theme — Windows 2000
   ---------------------------------------------------------------------------
   One stylesheet, four skins, two colour schemes.  Every surface is built out
   of the same three things the classic Win32 widgets were: a two-tone bevel
   (outer 1px highlight/shadow, inner 1px light/dark), a dither pattern where
   the OS used 50% checkerboards, and -- for meters -- a repeating gradient
   whose stops make the LED-style segments.

   The skin matrix is chosen with `body[data-skin]` and the scheme with
   `body.light`, both set before first paint by the inline script in
   index.html.  No attribute at all means Windows 2000, dark.

   Layout note: the whole page is one application window sitting on a desktop,
   and every card inside it is a smaller window of the same construction, which
   is why `.win`, `.raised`, `.sunken` and `.title-bar` carry most of the
   weight here.
