   reader.css — 阅读页增强（nocturne / 夜读）
   说明：
   - 阅读页的「基础排版 / 响应式 / 侧栏 / 面板」已由 app.css 的
     “章节阅读” 区块统一样式负责（serif 字体、两端留白、min(900px,100%)
     自适应宽度、金色分页、侧栏贴边、面板抽屉、小屏隐藏侧栏等）。
   - 本文件做 app.css 尚未覆盖的“增强”，并修复关键阻塞：
     read.css 仍写死 html{min-width:990px}，会阻止响应式生效，这里解锁。
   - 加载顺序在 read.css 之后、app.css 之前；与旧 CSS 冲突的属性用
     ID 级 !important 压制（ID 特异性 > 类，不受加载顺序影响）。

   设计目标：
   1) 桌面（≥1081px）：左右侧栏垂直居中贴边，金色线描按钮；
   2) ≤1080px：侧栏转为「底部悬浮操作簇」——左簇（目录/设置/书架/听书）
      + 右簇（收藏/评论），任何宽度都有功能入口，不再整体消失；
   3) 二维码卡片在窄屏隐藏；所有按钮 ≥44px 触控目标；
   4) 定位用 top/bottom + margin:auto 居中，不用 transform，
      避免劫持 fixed 抽屉（设置/目录/评论）的包含块。
   冲突压制：legacy read.css 用 ID 选择器（#right_bar_box 等），
   app.css 用类选择器且最后加载，故本节全部用 ID 级 !important。

   1) app.css 给 .left_panel/.db_box/.setUp_box/.comments_box 追加
      top:0;bottom:0，与 legacy ID 级 position:absolute 组合后，
      目录/设置面板被压成侧栏自身高度（约 300px）且内容溢出；
   2) legacy .comments_box 的 margin-left/top:10% 未被重置，
      右侧抽屉整体偏移、高度过约束；
   3) 听书面板 top:0 相对中部磁贴向下伸 480px，底部溢出视口。
   方案：全部改为视口级 fixed——目录/设置为侧栏右侧居中面板，
        评论为右侧抽屉；≤1080px 转居中模态 / 底部弹层。

   历史问题：legacy read.css 里 .brown/.green/.pink/.blue/.gray/.black

   所以设置面板的“阅读主题”看起来无效。
   这里按主题定义独立变量，并作用到阅读卡片、标题、正文、翻页键。
   深色阅读器使用“暗色纸张”方案，避免整页突然变白。
