/* Responsive Design.
   The 300px site sidebar goes full-width below 980px; on the way down the
   three columns would clip the 800px board, so the dead-simple ordering
   below is intentional: side-by-side while everything fits, stacked once the
   board could no longer keep a tournament size. The side panels keep their
   own widths and each track stays minmax(0, …) so nothing can overflow. */
