 - Whole UI restyled to a warm library palette (stone surfaces + amber accents, replacing cool zinc + emerald): warmer dark chrome, amber primary buttons/links, hover/press feedback on shelf cards (cover lift + glow), reader header with format badge and blur, pill-style CBZ page indicator, EPUB spread centered like a book page.
 - 全站换为暖色「书房」配色（stone 深灰面 + amber 琥珀强调，替代冷色 zinc + emerald）：书架封面悬停上浮高亮、阅读器顶栏带格式徽章与毛玻璃、CBZ 页码改为悬浮胶囊、EPUB 页面居中成书卷感，主按钮/链接统一琥珀色并补齐悬停/焦点反馈。

+- The admin 删除 button is gone from the reader header: deleting books now lives only in the shelf cover-card hover action, so a destructive tap can't happen one step away from the page-turn zone while reading.
+- 阅读器顶栏右上角不再提供 admin「删除」按钮:删除入口仅保留在书架封面卡片的悬停操作中,避免阅读时误触翻页区旁的破坏性删除。

 ### Fixed / 修复
 
 - Comic continuous-scroll mode is contiguous again on phones: the size observer used to miss the scroll container (it was attached while the reader still showed "loading", so the box didn't exist), leaving page geometry computed from a stale 480px default width while pages rendered at the real (e.g. 390px) width — every page gained a constant dead gap. The observer now attaches when the box actually mounts; additionally, mobile address-bar show/hide no longer rebuilds the scroll geometry in continuous/whole-page modes, which used to wipe measured page heights and re-trigger a burst of image requests.
