 ### Changed / 变更
 
+- Reader chrome is no longer text-only: lucide icons accompany 导航/上一章/下一章/翻页/抽屉选项卡/书签操作, while 连读 and 预读 (now a 0–3 slider) collapse into a 更多 menu in the CBZ bar.
+- 阅读器工具条告别纯文字：导航/上一章/下一章/翻页/抽屉选项卡/书签操作均配 lucide 图标；连读与预读（改为 0–3 滑条）收进 CBZ 工具条的「更多」菜单。
+
 - Reader navigation tightened into one left-side drawer opened by a single 导航 toolbar button: 目录 and 书签 are now tabs of a sidebar shared by all four readers, following the reader theme's colors; the button lands on 目录 when a TOC exists, otherwise straight on bookmarks (flat archives, EPUB, PDF show no tab bar); 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，工具条只留一个「导航」按钮：目录与书签成为四个阅读器共用侧边栏内的两个选项卡，配色跟随阅读器主题；有目录时默认落在「目录」，否则直达书签（平铺包、EPUB、PDF 不显示选项卡条）；原右侧书签面板与各阅读器自绘目录浮层移除。
