/* 资料阅读抽屉与资料选择器（material-reader.js）的样式：正式版第 4 轮 Part D（规格 D78、D80 的选择器部分、§12.5、23.76、23.96）。
   阅读器沿用搜罗预览的写法（search.css:211-247）：衬线标题、灰色小标签、细线分隔的资料信息、2px 深蓝左线的原文 / 中文对照块；
     抽屉 ≥481px 宽 min(1180px,94vw)，标题栏固定、正文区自己滚动、视图条在正文区内吸顶；≤480px 为铺满宽度的底部弹层（拖动条、圆角在上）；
     视图条为文档页的下划线标签（topic-list.css 的做法），操作行另起一行；段落号“¶n”放在左侧窄栏、无衬线；引用段落用 --ss-highlight 底与 2px 声纳青内侧线；
     段落操作为安静的文字按钮，≤800px 时为 44px 高的触控按钮。
   选择器（dialog.material-picker-dialog，资料选择与报告引用表共用）：白纸、衬线标题、正式表格语法（无灰色表头底，表头小字加墨色细线，行间细线，已选行不着色）。
   覆盖的旧规则：tag-workspace.css:4、8、9、13、15、16，site.css:51-55、210-221，workspace.css:16、24，workspace-improvements.css:19-20、27-49，report-translations.css:57-60，
   formal-theme.css:333-335（窄屏抽屉规则不含阅读器）。本文件在它们之后加载，选择器至少与旧规则同级。
   断点 480 / 800 / 1100 / 1280；颜色只用 var(--ss-*) 令牌（深色主题由令牌切换）；不用 !important，不写内联样式；强制配色、打印与减少动态效果各有对应规则。 */
