/* ===== 翻页条（日志 / 任务 / 索引卡片 / 工作流数据列表共用）=====
   用户提过两次：
     ·「日志中的页数选择改为悬浮」——要一直够得着，不用滚回列表末尾；
     ·「悬浮选择位置不好，请优化一下」——以前是一条横贯整屏的长条贴在底部，
       看着像页面多了一条边，还会压住最后几行。
   现在是一条**居中的窄胶囊**：只占自己那么宽，悬浮在视口底部中间，
   左右留白，不挡侧栏也不压住整行内容；按钮做成圆形小键，页码是等宽数字。
   容器用 width:fit-content + margin:auto 居中，所以不会出现「整条都能点」的
   透明区域挡住下面的内容。
   bottom 里的 --view-pad-bottom 是在抵消 .view 自己的底部内边距：
   sticky 定位只在内容盒里生效，不抵消的话翻页条会停在离屏幕底 95px 处
   （用户第二次提「悬浮选择位置不好」，就是被这层内边距顶上来的）。 */
