   control audit then has to hand-model that plugin's base layer and assert the

   Its effect comes from the UA stylesheet's `[hidden] { display: none }`, which
   any author rule setting `display` beats on specificity. So the moment a
   component gets `display: inline-block` or `display: grid`, every element of
   that kind marked hidden becomes visible again -- and nothing in the markup or
   the JavaScript looks wrong, because both are correct. One rule, at the top,
   for every component in the app. */
