 *   1. Modal was auto-opening on page load because `display: flex` was
 *      overriding the [hidden] attribute's default `display: none`.
 *   2. RTL arrows pointed the wrong way — swap positions AND swap the arrow
 *      characters so left/right feel correct in a right-to-left flow.
 *   3. Cover images that fail to load now show a nice gold-on-navy placeholder
 *      with the year, so the cards never look broken.
 * ══════════════════════════════════════════════════════════════════════════ */
