/*
 * Web Comic Reader — styles.css  v2.2.3
 *
 * CHANGELOG
 * ─────────────────────────────────────────────────────────────────────────
 * [FIX v2.2.3] Dock redesigned to match DHLKeyuser live site:
 *   • #webtoonDock is always a fixed bottom bar, never auto-hidden.
 *   • .webtoon-dock-handle shows only page counter + chevron toggle.
 *   • .webtoon-dock-content holds the full #readerToolbar, expanded by
 *     default. Chevron rotates to indicate state.
 *   • No .auto-hidden class or scroll-direction hide logic.
 *   • Paged mode: dock still shows, zoom/gap controls visually disabled.
 *   • --dock-height CSS var used to add bottom padding to both
 *     #scrollContainer and #pagedContainer so content is never obscured.
 * [FIX v2.2.2] float:none guard retained.
 * [FIX v2.2.1] Dropzone vendor-prefix warnings removed.
 * ─────────────────────────────────────────────────────────────────────────
