/* ==========================================================================
   ShadowShells stylesheet.

   Target: a shell-provider site circa 2000-2003 -- EuShells, NordicBots,
   QuakeNet and the rest. The defining traits of that look, all deliberate
   here: a fixed-width centred column sized for an 800x600 screen, a left
   sidebar of navigation boxes, every content block inside a 1px-bordered
   box with a coloured title bar, small Verdana/Tahoma text, dense spacing,
   and bright accent links on a dark ground.

   SINGLE THEME, ON PURPOSE. Sites of this era had exactly one appearance;
   a light/dark toggle is precisely the modern affordance that made the
   previous design read as new. There is therefore no prefers-color-scheme
   block -- but every colour is still declared explicitly, and the body
   paints its own background, so the page never inherits a host theme.
