/* ==========================================================================
   资产页（生成历史 / 主体）版式改版 —— 2026-09

   目标：保留站内既有能力（主体库、加入主体库、批量选择、分类、@ 用于生成），
   只重做整体布局、字体与间距：左侧分类标签 + 右上角紧凑操作区 + 按日期分组
   的无缝瀑布流，缩略图信息与操作收进悬停浮层。

   本文件在 styles.css / replica-theme.css 之后加载，用来覆盖旧版资产样式，
   因此选择器统一带 .client-body 前缀以保证优先级。
   ========================================================================== */
