新增全局 Toast 容器、反馈服务和状态 Hook，统一各页面操作反馈及加载失败重试。同步材料来源应用名称、业务流程和设计文档，并更新应用版本。

 页面 `className` 仅承担 flex、grid、宽度、间距、对齐、滚动和响应式。背景、颜色、描边、圆角、阴影及交互状态由官方 variant、compound API 和上述共享样式负责。
 
+## 操作反馈浮层
+
+接口成功、失败及降级警告统一使用应用根部 `AppFeedback` 的 HeroUI `Toast.Provider`；登录、独立流程页和 AppShell 共用一个容器。最多显示 3 条，成功默认 4 秒、错误/警告默认 8 秒后消失，关闭不改变请求结果或表单草稿。
+
+同步问题整改应用 `bfc5862` 的关闭按钮：组合官方 HeroUI `Button`（`ghost`、`sm`、`isIconOnly`）和 `AppIcons.Close`，通过 `slot="close"` 接入关闭行为。按钮在正文右侧参与布局，前排图标始终可见，后排堆叠提示隐藏关闭按钮；不设置额外绝对位置、边框或正文右侧占位，沿用官方 Hover、焦点和主题样式。
+
+`src/tailwind.css` 负责安全区位置、层级 300、14px 圆角、局部进入动画和后排按钮可见性，保证提示高于业务弹窗和移动侧栏。保留独立 `feedbackQueue` 的同步更新，不触发整页 View Transition，关闭提示不会误点弹窗遮罩。详情保存成功反馈使用 `useFeedbackState('success')`，随编辑会话和记录切换清理。

 ## 品牌与图表色板
 
 - 鑫元品牌主色固定为 `#DA241A`。HeroUI v3 的 `--accent`、`--accent-hover`、`--focus` 以及共享 `--rc-brand-primary` 均不得被页面或深色主题改写为其他色相；primary 色阶仅作为兼容别名维护。

+- 登录、应用切换、业务列表、新增/编辑详情、自查填写与审核、通知中心、材料查询/上传及远程引用/人员搜索共用应用根部的 HeroUI Toast 容器，最多展示 3 条提示。提示固定在视口顶部中央，层级高于弹窗和移动端侧栏，不占用页面布局，也不随列表或弹窗正文滚动。
+- 保存、新增、删除、归档、导出及通知操作成功后显示短暂成功提示，约 3–4 秒自动消失；接口失败或配置回退显示错误/警告提示，约 8 秒自动消失，悬停或键盘聚焦暂停计时。当前提示右侧的关闭图标始终可见，使用 HeroUI 小号透明图标按钮，通过官方 `close` slot 支持点击与键盘关闭，移动端同样可直接关闭；后排堆叠提示隐藏关闭按钮，避免误关闭。相同错误在再次请求失败时重新提示。
+- 提示关闭只影响展示，不改变请求结果、权限、记录状态或表单草稿。新增/编辑失败保留当前草稿，自查流程保存失败保留未保存修改；字段必填、JSON 校验和记录锁定等需要修正或了解的字段状态继续在对应位置展示。
+- 详情弹窗点击“保存”后，只有待建档材料及 `PUT /record/:name` 全部成功，才退出编辑并显示“详情已保存。”成功提示；弹窗继续展示已保存内容。重新编辑、再次保存、取消编辑、关闭弹窗或切换记录时清理上一条成功提示；无字段修改、校验未通过或正在保存时不提交、不显示成功提示。任一接口失败保留当前草稿并显示错误，重试沿用第 10 节的材料建档规则。
+- 列表、通知、自查流程及详情首次加载失败时保留失败空态和重试入口；材料查询失败时保留“重新加载材料”按钮，引用/人员候选列表保留失败状态并允许重新搜索。应用配置或应用列表回退警告也通过 Toast 展示，不再使用常驻接口反馈横条。
+- Toast 使用 HeroUI 的可访问通知区域与语义状态图标，长错误文案换行并限制高度；请求与写入继续使用第 8 节的接口、原 Subject 字段及 `metadata` 协议。
+- 提示使用独立 HeroUI 队列和局部进入动画，不触发整页 View Transition 快照；提示出现后立即点击“关闭提示”也只关闭该提示，不会误触弹窗遮罩。
