+# YoVision 当前 MVP 交互原型
+
+本目录是工单 #28 生成的版本绑定设计资产，用于确认 MVP #8 的信息架构、页面状态和交互流程，不代表产品功能已经实现。
+
+## 打开方式
+
+可直接双击 `index.html`，或在仓库根目录启动本地静态服务：
+
+```powershell
+python -m http.server 4173 --directory prototypes
+```
+
+然后访问 `http://127.0.0.1:4173/`。
+
+## 原型范围
+
+- `sense/index.html`：设备接入、ONVIF/RTSP、MediaMTX、实时监看和区域配置；直接映射 go-admin-ui 与 Element Plus 的通用管理端组件。
+- `brain/index.html`：合成输入到项目内匿名事件的内部流水线；Brain 无客户管理 UI。
+- `bell/index.html`：合成事件、不可变 Event、规则/Alert、ack/close 和审计时间线；直接映射 go-admin-ui 与 Element Plus 的通用管理端组件。
+- `assets/`：三套原型复用的基础样式和交互脚本；Sense/Bell 共同复用 go-admin-ui 原型外壳适配器。
+- `design-system/yovision/MASTER.md`：由 UI/UX Pro Max 生成的设计系统基线。
+
+## 交互提示
+
+- 左侧导航可切换页面；移动端使用顶部菜单按钮。
+- Sense 可筛选设备、添加待激活设备并查看区域配置。
+- Brain 可模拟处理下一帧并生成项目内事件。
+- Bell 可注入合成事件，并演示 Alert 的 ack 和 close。
+- 所有弹窗支持 `Esc` 关闭，交互元素支持键盘焦点。
+
+## Sense / Bell 的 go-admin-ui 对齐基线
+
+- 只读参考仓库：`D:\github\goadmin\go-admin-ui`。
+- 参考 commit：`67d393d713877572fab0b897296a4c1d525fc81d`。
+- 应用外壳映射：`Sidebar`、`Navbar`、`TagsView`、`AppMain` 和 `BasicLayout` / 页面容器。
+- 通用组件映射：Element Plus 的 Button、Form、Input/Select、Table、Pagination、Dialog 和 Tag，以及 go-admin-ui 的搜索区与 `v-permisaction` 权限按钮模式。
+- 共用原型适配器：`assets/go-admin-ui.css` 与 `assets/go-admin-shell.js`；两套产品不复制应用外壳和通用组件原型代码。
+- Sense 专用组件：视频舞台 `SenseVideoStage` 与区域画布 `SenseZoneCanvas`。
+- Bell 专用组件：值班处置工作台 `AlertWorkbench` 与审计时间线 `AlertAuditTimeline`。
+- 新增专用组件前必须先确认 go-admin-ui / Element Plus 中没有等价组件。
+- 原型仍是无构建依赖的 HTML/CSS/JavaScript，并未嵌入或复制 go-admin-ui / Element Plus 源码；这些名称用于约束正式 Vue 实现的组件落点。
+
+## 事实来源边界
+
+- 产品范围以 Gitea Wiki 的 Product Requirements、Product Roadmap 和对应工单为准。
+- 本原型不定义 API、数据库或跨项目契约。
+- 旧仓库原型仅用于只读参考；本目录没有复制旧原型代码。
+- 页面数据均为虚构演示数据，不得放入真实账号、摄像头凭据、客户数据或生产地址。

+  border-radius: 16px;
+  padding: 32px;
+  box-shadow: var(--shadow-xl);
+  max-width: 500px;
+  width: 90%;
+}
+```
+

+
+## Style Guidelines
+
+**Style:** Data-Dense Dashboard
+
+**Keywords:** Multiple charts/widgets, data tables, KPI cards, minimal padding, grid layout, space-efficient, maximum data visibility
+
+**Best For:** Business intelligence dashboards, financial analytics, enterprise reporting, operational dashboards, data warehousing
+
+**Key Effects:** Hover tooltips, chart zoom on click, row highlighting on hover, smooth filter animations, data loading spinners
+
+### Page Pattern
+
+**Pattern Name:** Real-Time / Operations Landing
+
+- **Conversion Strategy:** For ops/security/iot products. Demo or sandbox link. Trust signals.
+- **CTA Placement:** Primary CTA in nav + After metrics
+- **Section Order:** 1. Hero (product + live preview or status), 2. Key metrics/indicators, 3. How it works, 4. CTA (Start trial / Contact)
+
+---
+
+## Motion
+
+**Page Transition** (Subtle) — Trigger: route change | Duration: 200-300ms | Easing: `power1.inOut`
+
+```js
+gsap.to(main, { opacity: 0, duration: 0.2, onComplete: () => { navigate(); gsap.fromTo(main, { opacity: 0 }, { opacity: 1, duration: 0.2 }); } });
+```
+
+**Framework notes:** Pair with the router's transition hooks (Next.js App Router transitions, React Router's useNavigate, Vue Router's beforeEach/afterEach)
+
+- ✅ Preload the destination route's critical assets before the exit tween finishes
+- ❌ Don't block navigation on animation; cap exit duration at ~250ms so the app never feels unresponsive
+- ⚡ Exit animation should always resolve faster than entrance (asymmetric timing) so back/forward feels snappy
+
+---
+
+## Anti-Patterns (Do NOT Use)
+
+- ❌ Ornate design
+- ❌ No filtering
+
+### Additional Forbidden Patterns
+
+- ❌ **Emojis as icons** — Use SVG icons (Heroicons, Lucide, Simple Icons)
+- ❌ **Missing cursor:pointer** — All clickable elements must have cursor:pointer
+- ❌ **Layout-shifting hovers** — Avoid scale transforms that shift layout
+- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
+- ❌ **Instant state changes** — Always use transitions (150-300ms)
+- ❌ **Invisible focus states** — Focus states must be visible for a11y
+
+---
+
+## Pre-Delivery Checklist
+
+Before delivering any UI code, verify:
+
+- [ ] No emojis used as icons (use SVG instead)
+- [ ] All icons from consistent icon set (Heroicons/Lucide)
+- [ ] `cursor-pointer` on all clickable elements
+- [ ] Hover states with smooth transitions (150-300ms)
+- [ ] Light mode: text contrast 4.5:1 minimum
+- [ ] Focus states visible for keyboard navigation
+- [ ] `prefers-reduced-motion` respected
+- [ ] Responsive: 375px, 768px, 1024px, 1440px
+- [ ] No content hidden behind fixed navbars
+- [ ] No horizontal scroll on mobile
