   EastCoast ~ PvP ~ site.css
   One document, four panels side by side: Server, Plugins,
   Changelog, Range. Horizontal moves between panels, vertical
   reads within one. With JavaScript off the panels stack.

   Deliberately absent:
     - gradients of any kind
     - backdrop-filter / glass
     - bordered pills and chips
     - entrance animation on list items
     - uppercase tracked labels as a house style
