/* The [hidden] attribute and a class like .dl-card (display: flex) have equal
   CSS specificity — whichever is declared later in the cascade wins, and an
   author-stylesheet class rule always comes after the browser's built-in
   [hidden] rule. Without this, any element that's both .dl-card and [hidden]
   stays visible (and clickable) despite being "hidden" — this was silently
   true for every such element in the app until now. !important forces
   [hidden] to always win regardless of what other display rules a hidden
   element's classes carry. */
