 - 应用落地：business 模块自定义弹窗——`common-route.vue` 的「选择常用地址」弹窗用 section-card 包成「查询条件/常用地址」两组；`loading-manage.vue` 主弹窗 6 个分区全部改用 `<section-card>`；`common-cargo.vue` 导入弹窗经全局 `.el-dialog .avue-form` 规则自动获得白卡。`project-apply.vue` 本身作为参照未改（其 scoped 样式已符合，全局灰底与其一致）。
 - 验证：`vite build` 失败为仓库既有问题（`waybill-import-dialog.vue` 引入的 `xlsx` 依赖缺失），与本次改动无关；改用 `@vue/compiler-sfc` 编译三个改动 .vue（均 OK）+ sass 编译 `element-ui.scss`（OK）。
 - 注意：其他模块的**自定义弹窗**需按同样方式用 `<section-card>` 包裹各组（灰底已由全局规则自动生效）；如需继续推进其余模块可照此模式批量处理。
+
+## 继续推广：vehicle/customer-archive.vue 弹窗
+- 用户反馈 `/vehicle/customer-archive` 新增客商档案弹窗需与 `/business/project-apply` 一致。
+- 已将该页主弹窗内的表单分组由旧版「灰底分组块 + 内层白卡 + 标题在卡内」全部替换为 `<section-card>`：
+  - 工商信息 / 联系信息 / 财务/信用信息 / 其他信息 四个分组改为 section-card；删除外层浮于灰底的「基本信息」大标题（分组已足够清晰，避免嵌套）。
+  - 客商材料、变更记录两个非表单分区也改用 `<section-card>`，其中客商材料的操作按钮通过 `#extra` 插槽放在卡头右侧。
+- 清理了失效的 `.archive-form__group`、`.customer-material-section`、`.change-record-section`、`.section-title` 等 scoped 样式。
+- 验证：`@vue/compiler-sfc` 编译 `customer-archive.vue` OK；sass 编译 `element-ui.scss` OK；section-card 标签开合平衡。
