/* 资料库（library.js，/research/materials；第 4 轮 Part L，规格 §12、D74–D77、D79、D80、23.69–23.75）的样式。
   页面根 main > .doc-page.list-page.library：衬线 h1、页头底部墨色细线与正式表格来自 pages.css；预览与底部弹层沿用 search.css 的类名（.search-preview、.search-sheet、.preview-*）。
   本文件：页头一行（标题 · 按标题查找 · 导入资料 · 重复候选）与说明句中的“搜罗”入口；筛选行（来源标签按钮、两个下拉、清除筛选）；
   列表头、正式表格的列宽（32 | 1fr | 128 | 104 | 72）、行内标题与一行要点（读取前为一行骨架）；列表 + 右栏预览的栅格（≥1280 为 380、1101–1279 为 320、≤1100 单栏改用弹层）；
   吸底已选条（2px 海军蓝顶线 + 渐隐带）、分页与空状态；导入资料、批量中文整理与重复候选三个对话框（#modal 内，按内容用 :has 调整宽度）；
   ≤800 每行改为两区、≤480 点按区 44px；强制配色、打印与减少动态效果。
   颜色只用 var(--ss-*) 令牌（深色主题由令牌切换）；不写内联样式；预览栏限高由 library.js 在本文件末尾插入的 .library .search-preview 规则写入 --search-preview-max（CSSOM）。 */
