/* The UA stylesheet applies `hidden` as `[hidden] { display: none }` at the same
   specificity as a class, so any later class that sets `display` silently wins
   and the element stays visible. Every view here is toggled with `hidden`, and
   the modal has a full-screen overlay — when it leaked through, it swallowed
   every click on the page. Make `hidden` mean hidden. */
