 - CBZ reader is now chapter-scoped: a chapter's images flow as one continuous strip and scrolling stops at an 本章完 · 下一章 card (only chapter buttons / TOC / slider / bookmarks cross the boundary); a 连读 toggle makes scrolling flow across chapters, and a configurable 0–3-chapter prefetch pre-mounts upcoming chapters for instant switching — the old 连读/整页/适高 mode cycle is gone.
 - CBZ 阅读器改为以章为单位:一章图片是一段连续长卷,滚动止于「本章完 · 下一章」卡片(跨章只能靠章节按钮/目录/滑条/书签);「连读」开关让滑动贯穿章节,预读 0–3 章可配置、提前挂载解码实现切章零白屏;移除原 连读/整页/适高 三档循环。

 ### Changed / 变更
 
+- Reader navigation tightened into one left-side drawer: 目录 and 书签 are now tabs of a single sidebar shared by all four readers, following the reader theme's colors (books without a TOC — flat archives, EPUB, PDF — show the bookmarks panel alone); the separate right-side bookmark panel and the per-reader TOC popovers are gone.
+- 阅读器导航收紧为统一左侧抽屉：目录与书签成为四个阅读器共用的同一侧边栏内的两个选项卡，配色跟随阅读器主题（无目录的书——平铺包、EPUB、PDF——仅显示书签面板）；原右侧书签面板与各阅读器自绘目录浮层移除。
+
 - The web UI was rebuilt on a shadcn/Radix design system: semantic light/dark theme tokens with a system/light/dark switcher (remembered), a persistent app shell (desktop sidebar, tablet icon rail, mobile bottom tabs), a shelf driven by URL-state search/sort/group controls with a flat-first grid and menu-based card actions (confirm dialogs replace native popups), and rebuilt login/admin pages. Readers keep their current chrome and every reading interaction this round; their restyle lands next.
 - 网页 UI 以 shadcn/Radix 设计系统重做:语义化明暗主题 token + 系统/浅色/深色切换(记忆);常驻应用壳(桌面侧栏、平板图标栏、手机底部标签);书架改为 URL 状态驱动的搜索/排序/分组工具条,默认平铺网格,卡片操作收进菜单(删除改为对话框确认);登录页与 admin 两页同步重做。阅读器保持现状,改版随下一期到达。
