/* This must win over every other display rule in this file. Several classes
   below (.btn, .pos-tile, .modal-overlay, etc.) set their own `display`, and
   a plain class selector has the same specificity as the `hidden` attribute
   selector the browser uses internally — so without !important here, an
   element that is BOTH e.g. `class="btn"` and `hidden` stays visibly on
   screen: the JS correctly toggles the attribute, but the class's `display`
   silently wins the cascade and nothing appears to happen. This was the
