+# UI 编辑器工作流完成通知弹窗
+
+## 目标
+
+UI 编辑器的“分析参考图”“识别界面结构”“绑定视觉素材”三个工作流动作在每次运行结束后，用独立的阻塞通知弹窗明确反馈结果，避免仅依赖卡片内一行状态文本而被忽略。
+
+## 交互约定
+
+- 三个动作的每次运行在终态（成功或失败）时自动弹出一次通知。
+- 弹窗打开期间遮挡并阻塞工作台底层交互；关闭后恢复当前步骤，不自动切换步骤、不自动重跑。
+- 使用现有 `ThemedModal` 的普通关闭行为（遮罩、Esc 和关闭按钮均可关闭）。
+- 弹窗仅承载通知，不提供“继续”“重试”或其他业务操作。
+- 关闭弹窗后，工作流卡片继续显示同一条结果状态；重新运行产生新的终态时再次通知。
+- 绑定动作包含多个批次时，只在最终批次结束后通知一次。
+
+## 文案
+
+弹窗标题由步骤名和结果态组成，例如“识别界面结构完成”或“绑定视觉素材失败”。正文复用卡片状态文本，并逐条扩展结果信息，统一以“请检查”收尾。
+
+成功状态的基线文案：
+
+- 分析参考图：保留已应用的语义建议数量；若现有状态可可靠取得问题/待确认数量，则一并展示。
+- 识别界面结构：保留替换的界面树数量，并展示识别结果中的待检查/必须修复数量（若可取得）。
+- 绑定视觉素材：保留现有 `B/B` 批次计数，改为用户可读的绑定结果。
+
+失败状态保留实际错误文本，仅在弹窗标题中补充步骤和失败上下文，正文同样以“请检查”收尾。
+
+## 实现边界
+
+- 新增独立的工作流通知弹窗组件文件，组件只负责展示和关闭，不包含工作流领域规则或后端副作用。
+- 在 UI 编辑器页面/会话投影中维护临时通知状态，并在三个异步动作的成功与失败终态写入。
+- 不新增后端字段或公开契约；数量只能使用当前前端已有且可靠的数据。
+
+## 验收
+
+1. 三个动作成功和失败终态各弹出一次通知；绑定批次只弹最终一次。
+2. 弹窗打开时底层工作台不可操作，且无继续/重试等业务按钮。
+3. 弹窗可通过标准关闭方式退出；关闭后卡片状态仍可见。
+4. 每条成功文案保留原有数量信息并增加可用的检查数量，所有文案包含“请检查”。
+5. 重新运行后新的终态会再次弹出通知。

+## 交付目标

+## 交互约定
+
+- 滑杆选择范围为 25%–200%，步进 5%；快捷加减继续使用核心视口的现有缩放边界。
+- 滑杆位于预览区右下角固定工具栏；不提供移动端或窄窗口 fallback。
+- 保留 `−` 与 `+` 按钮。点击轨道可跳转，拖动滑块实时更新画布和百分比。

+- 百分比文本使用数字输入框呈现；输入提交后同步视口缩放，适配画布保持独立按钮，点击百分比不会触发适配。
+- 缩放滑杆获得焦点时，Delete/Backspace 不触发 UI 节点快捷删除；缩放按钮鼠标点击不改变快捷键焦点。
+- Windows/Linux 使用 `Ctrl`，macOS 使用 `Cmd`；`+`、`=` 与 `NumpadAdd` 放大，`-` 与 `NumpadSubtract` 缩小，允许按键重复时连续缩放。
+- 快捷键直接复用现有 `+`/`−` 按钮动作：以视口中心为锚点，按 `×1.16`/`×0.86` 改变缩放。
+- 鼠标悬停在预览画布上，或预览画布已获得键盘焦点时，快捷键生效。预览画布需提供可聚焦语义与无障碍名称。
+- 事件来自输入框、文本编辑区、按钮、链接、缩放工具栏或其他可操作控件时不拦截；不向 iframe 子文档注入监听。
+- 仅在存在可缩放视口且确认命中快捷键时调用 `preventDefault()` 与 `stopPropagation()`，防止浏览器页面同时缩放。
+- 保留现有 `Ctrl/Cmd+0` 适配画布与 `Ctrl/Cmd+1` 恢复 100% 行为，不增加其他重置快捷键。缩放仍是当前预览实例的临时 UI 状态。
