/* ============================================================
   FIX: [hidden] attribute must override display:flex/grid

   By default the user agent stylesheet has `[hidden] { display: none }`
   with very low specificity, so any class rule with `display: flex`
   wins and a hidden=true element stays visible. We override here.
