 2026-10-20 独立样式审查收尾：采购详情删除局部.purchase-detail的旧border/radius/background，外框由workbench-panel统一维护，业务布局保留。4个页面文件的模板/样式编译及公共外观归属检查通过，相关4文件58项回归通过，差异检查通过；人工截图仍待确认。
 
 2026-10-20 用户追加整页白底修正：整页主要列表外层workbench-table及整页详情workbench-panel显式增加is-page-surface，由公共样式移除最外圈border/radius/shadow。内部指标、图表、并列卡片、子表格线、弹框和日历左右独立面板保留；本批不改padding、脚本或承载。

+
+| 页面/文件 | 操作与既有承载 | 结构问题与修复 | 验收 |
+|---|---|---|---|
+| ProcurementNodeActions | 采购详情中的节点命令居中弹框 | 自定义footer绕过AppDialog默认操作区容器；三项操作加入density-actions底部容器，允许换行并保持间距 | 定向回归通过；待人工1920×1080、100%截图确认 |
+
+保持既有命令、草稿、未知结果核对、权限与提交条件；只新增操作区容器。公共AppDialog的直接按钮footer修复由公共样式写者维护，本域未修改公共组件。
