/* Several components below (.fp-sheet-overlay, .fp-cart-bar, ...) set their
   own `display` unconditionally. A class selector and the `[hidden]`
   attribute selector have equal CSS specificity, so without this rule the
   browser's built-in `[hidden] { display: none }` loses to those classes
   and toggling `el.hidden` in JS has no visual effect - the product sheet
   overlay and cart bar end up permanently rendered full-screen/fixed,
   dimming the page and swallowing every tap regardless of what's
   underneath. This override always wins. */
