 - 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。
 
-- Bookmarks in all four readers: a 书签 button in the bar captures the current position (page / chapter+offset / EPUB CFI) with an optional note; the right-side panel lists them — click jumps straight back to that spot, ✎ edits the note in place, ✕ deletes. Bookmarks are per-user and server-side, so they follow you across devices.
-- 四类阅读器新增书签：工具条「书签」按钮把当前位置（页码/章节+章内偏移/EPUB CFI）连同可选备注存下；右侧书签面板点一下即跳回原位，✎ 行内改备注，✕ 删除。书签按用户存在服务端，换设备同账号即见。

-- Folder-structured comics gain a 目录 sidebar in the CBZ reader: each archive folder (第N話…) becomes a chapter that jumps to its first page, with 上一章/下一章 buttons, a current-chapter counter, and the active row highlighted and scrolled into view — flat archives show no extra UI.
-- 按目录组织的漫画在 CBZ 阅读器新增「目录」侧栏：压缩包内每个文件夹（第N話…）即一章，点击直达该话首页；工具条配上一章/下一章与当前章计数，目录内高亮当前章并自动居中；平铺无目录的包不显示多余控件。

 - Library uploads over 16MB now auto-switch to the resumable chunked protocol (8MB parts): failed parts retry in place up to 3 times and already-sent parts are skipped, so a flaky upload continues instead of starting over; small files keep the original single request.
 - 书库上传超过 16MB 自动切换为可续传分片协议（每片 8MB）：失败的分片原地重试至多 3 次，已传片自动跳过，中断后继续而不是从头再来；小文件仍走原单次上传。

 ### 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。
