/*
 * Changelog 3.0.1
 * - Fix: modal overlay no longer removes `display` on close, so fade-out works and
 *   the modal does not vanish inside clipped / backdrop-filter ancestors.
 * - Fix: header search bar uses display toggle (no more `overflow: hidden` clipping
 *   live search results).
 * - Fix: mobile menu uses display toggle + desktop guard so it never shows on desktop.
 * - Fix: hero decorative circles converted to background gradients, removing
 *   `overflow: hidden` so live search results / modal can escape the hero box.
 * - Fix: chapter accordion no longer clips content taller than 1200px.
 * - Fix: body uses `overflow-x: clip` fallback to `hidden` to avoid breaking sticky/fixed.
 * - Fix: touch devices always show Quick View button and cover overlay.
 * - Add: scroll-margin-top on anchor targets so hash navigation clears the sticky header.
 * - Add: position:relative guard on .live-search-form.
