/* Shuffleboard.  One stylesheet, no framework, no external font, no external image.
   ------------------------------------------------------------------------------------------
   ONE RULE HERE IS LOAD-BEARING AND IS WRITTEN THE WAY IT IS ON PURPOSE.  `[hidden]` is only
   a UA rule setting display:none, and ANY class rule that sets display beats it - which
   produces an invisible overlay that still swallows every click.  So .modal is never given a display of its own: it is given one
   only under :not([hidden]), so hiding it cannot fail.  tools-harness-page.js parses this file
   and asserts that. */
