 * The hidden attribute must beat any display set by a class.
 *
 * The browser's own `[hidden] { display: none }` lives in the UA stylesheet,
 * which every rule in this file outranks. So `.overlay { display: flex }` quietly
 * defeated `hidden`, leaving an empty white overlay over the page from first
 * paint — and because closeOverlay() just sets `hidden = true`, the close button,
 * Escape, and tapping the backdrop all did nothing. The page was unusable.
 *
 * !important is deliberate: this has to hold no matter what any later class does,
 * since ten places in app.js toggle `hidden` and trust it to work.
