/* Global safety net: many components (.ep-btn, .ep-modal-overlay, etc.) set
   `display` directly on their own class, which has equal specificity to the
   browser's default `[hidden] { display: none }` rule -- author rules win
   ties, so without this, toggling `hidden` via JS silently does nothing on
   any element that also carries one of those classes. `!important` here
   guarantees `hidden` always wins, everywhere, regardless of what else is
   applied to the element. Toggle visibility with `el.hidden`, never
   `style.display`, and this keeps working correctly. */
