 - 数据处理页的容量数据卡片与 CellData 卡片左上角均显示数据类型，右上角均提供说明图标按钮，点击后以小弹窗展示所需文件格式和目录结构。
 - CellData 卡片改为点击/拖拽文件夹上传，不再提供单文件选择；直接拖入单个 ZIP 会提示选择包含 `Result_300` ZIP 的文件夹。
 - 验证：`frontend` `npm run build` 通过；构建产物已清理。
+
+## 2026-06-25：数据处理卡片并排展示
+
+- 数据处理页容量数据与 CellData 两个卡片在宽屏下左右并排展示，窄屏下自动回落单列，减少对日志区域的挤压。
+- 容量数据说明补充：启用 CellData 数据源时，处理容量数据前会先刷新 CellData；CellData 卡片按钮文案统一为「远程下载并处理」。
+- 验证：`frontend` `npm run build` 通过；构建产物已清理。
