+# VDI Cloud UI 设计稿
+
+基于「百工万象」定版界面的深色 / 浅色视觉语言，为 VDI Cloud 云桌面控制台整理的可交互设计稿。
+
+- `index.html`：设计稿入口，可切换深色 / 浅色与页面
+- `screens/`：渲染后的页面截图
+- `assets/`：品牌标识
+
+页面范围：云桌面总览、桌面资源池、远程会话、终端与策略设置。
+
+## ARM 终端设计稿
+
+真实终端界面请打开 `terminal/index.html`。它对应 `terminal/kiosk-shell/src/login_page.cpp`、`desktop_list_page.cpp`、`desktop_settings_dialog.cpp` 和 `main_window.cpp` 的流程，覆盖登录、桌面列表、连接中、重连、管理菜单五个状态。

+# VDI Cloud UI 设计说明
+
+## 视觉继承
+
+- **色彩**：以百工万象定版的蜂蜜金橙 `#BD713B` 为主动作色，配合深色 `#151D27 / #1D2733 / #253241` 与浅色 `#F5F7FA / #FFFFFF / #F0F3F7`。
+- **结构**：固定左侧组织与导航；右侧采用页面标题、动作区、卡片分组的工作台结构。
+- **组件**：18px 大圆角、轻阴影、低对比边框；状态使用绿/黄/红三色，保持与数字员工运行中心一致。
+- **交互**：页面在入口内可切换深浅主题；导航可以切换总览、资源池、远程会话、终端策略四个页面。
+
+## VDI 页面映射
+
+| 页面 | 目标 | 关键内容 |
+| --- | --- | --- |
+| 云桌面总览 | 管理员快速判断系统状态 | 在线桌面、活跃会话、延迟、告警、趋势、资源健康 |
+| 桌面资源池 | 管理桌面模板与分配 | Windows / Ubuntu 桌面卡片、GPU、分辨率、状态与连接 |
+| 远程会话 | 观察实时串流与诊断 | 画面预览、2K/60 FPS、延迟、GPU/显存、断开操作 |
+| 终端与策略 | 统一配置终端体验 | 显示规格、自动恢复、独立光标、USB、断线保护 |
+
+## 使用方式
+
+直接打开 `index.html`，点击左侧导航查看页面；点击右上角月亮/太阳按钮切换主题。

+# 越欣科技 ARM VDI 终端交互设计
+
+打开 `index.html`，从登录进入桌面列表。保留原有登录页 Logo、互动图形和深浅色外观，补充表单校验、登录状态及弹窗操作；登录后沿用深蓝灰 / 浅色和铜橙色按钮。
+
+## 登录体验
+
+公开体验账号：`demo`，密码：`Demo123!`。点击登录页的「体验账号」可查看并填入，再点击登录或按 Enter 继续。
+
+- 账号、密码为空时提示并聚焦；错误账号或密码会提示重试，清空密码。
+- 支持显示 / 隐藏密码、登录中状态和防重复提交。
+- 「记住工作账号」只保存成功登录的账号，不保存密码；取消勾选立即清除已记住的账号。退出后清空并隐藏密码。
+- 顶部「云端服务」打开连接设置，可切换云端服务 / 企业部署。企业地址需为 HTTPS，本机预览允许 HTTP；设置可保存、取消并在刷新后恢复。
+- 「企业 SSO」先检查企业连接配置，再展示体验身份；确认后进入桌面列表，取消或 Esc 会终止等待。
+- 「忘记密码」提供联系越欣科技管理员的说明及体验账号入口。
+- 「离线体验」确认后以独立体验身份进入桌面列表。
+
+这是交互原型，账号校验和 SSO 均为本地模拟，不会访问真实认证服务或远程桌面。请使用公开体验信息。设备和桌面数据为示例，未移植到 Qt 或部署到 ARM 设备。
+
+## 文件
+
+- `index.html`：登录界面和工作区挂载位置。
+- `login-interactions.js` / `login-interactions.css`：登录状态、校验、密码操作、连接设置、SSO 和弹窗样式。
+- `workspace.css`：登录后工作区的布局、配色、字号和适配。
+- `workspace.js`：桌面筛选、收藏、搜索、配置保存、连接状态、登录身份与设置导航。
+- `assets/systems/`：Windows、Ubuntu、麒麟识别资源。
+- [references/README.md](references/README.md)：Microsoft Windows App、Amazon WorkSpaces 实际截图，以及 Horizon 官方操作流程与设计采用理由。
+- `output/playwright/`：浏览器渲染与验证证据。
+
+## 评审入口
+
+- [review.html](review.html)：评审页，主入口从登录开始。
+- `index.html`：登录页。
+- `index.html?preview=desktops&theme=dark`：直接预览深色桌面列表。
+- `index.html?preview=desktops&theme=light`：直接预览浅色桌面列表。
+- `index.html?preview=settings&theme=dark`：桌面设置。
+- `index.html?preview=connecting&theme=dark`：连接中。
+- `index.html?preview=reconnect&theme=dark`：重连中。
+- `index.html?preview=error&theme=dark`：连接异常。
+
+正常流程：登录 → 桌面列表 → 设置或连接；`Ctrl+Alt+Shift+M` 打开管理设置，`Esc` 返回列表。设置中的「设备信息」提供退出登录。直接预览参数和管理快捷键仅用于原型评审，不代表生产权限控制。
+
+收藏、搜索、全部 / 已收藏筛选、设置分类、参数校验、保存、取消均可交互。账号、企业入口和桌面连接设置仅保存在浏览器本地。
+
+## 验证记录
+
+本次登录交互验证：[login-verification.json](output/playwright/login-verification.json)，包含账号登录、记住账号、服务地址校验、SSO 取消、离线体验、键盘操作和深浅色布局检查；截图以 `login-` 开头。
+
+此前桌面工作区记录：[verification.json](output/playwright/verification.json)。它记录工作区的 27 项流程与布局检查及补充检查；其中「登录与旧基线完全一致」「点击直接进入桌面」描述的是添加登录交互之前的版本，已由本次登录验证取代。桌面列表记录的最小文字对比度：深色 5.04:1、浅色 4.74:1。1280×720、1366×768、1920×1080 的浏览器检查不代表 ARM 实机验收。

+# VDI 终端界面参考与设计依据
+
+核对日期：2026-11-09。以下截图从官方文档的图片链接取得，作为研究材料保存在本目录，不放入产品界面。原始截图中的第三方品牌、组织和账号不用于越欣科技终端。
+
+## 1. Microsoft Windows App：桌面资源选择
+
+- 官方说明：https://learn.microsoft.com/en-us/windows-app/get-started-connect-devices-desktops-apps
+- Windows 客户端截图：https://learn.microsoft.com/en-us/windows-app/media/get-started-connect-devices-desktops-apps/windows-devices.png
+- Web 客户端截图：https://learn.microsoft.com/en-us/windows-app/media/get-started-connect-devices-desktops-apps/web-devices.png
+- 本地材料：[Windows 客户端](windows-app-devices.png)、[Web 客户端](windows-app-web-devices.png)。
+
+实际界面包含：设备页、桌面名称、服务类型、配置或组织、可连接状态、连接按钮，以及资源搜索和收藏入口。
+
+采用：以桌面名称为主标题，状态靠近名称；每张桌面有独立连接入口；支持搜索和收藏。
+
+调整：不采用截图的壁纸和文字叠层。越欣终端使用纯色卡片，让系统标识、名称、状态、配置、操作从上到下排列，消除深浅背景交叉造成的对比问题。三张桌面直接展示，不引入复杂导航或多工作区概念。
+
+## 2. Amazon WorkSpaces：资源管理、设置与会话诊断
+
+- 官方用户手册：https://docs.aws.amazon.com/workspaces/latest/userguide/amazon-workspaces-windows-client.html
+- 资源列表截图：https://docs.aws.amazon.com/images/workspaces/latest/userguide/images/wsp-windows-newclient-workspace-list.png
+- 显示设置截图：https://docs.aws.amazon.com/images/workspaces/latest/userguide/images/wsp-windows-newclient-display-fullscreen.png
+- 会话诊断截图：https://docs.aws.amazon.com/images/workspaces/latest/userguide/images/wsp-windows-newclient-session-health-panel1.png
+- 本地材料：[资源列表](workspaces-list.png)、[显示设置](workspaces-settings.png)、[会话诊断](workspaces-session-health.png)。
+
+版本说明：官方手册将该组新客户端界面标为 Public Preview；它是成熟 WorkSpaces 产品中的新界面参考，不表述为已全面发布版本。
+
+实际界面包含：收藏、资源名称与操作分离；设置按连接、显示、外观等类别组织；会话健康度以明确的网络状态和指标呈现。
+
+采用：收藏与连接互不混用；设置入口固定；配置字段有名称与说明；连接中、取消、错误恢复有明确路径。
+
+调整：当前 UI 原型不接入设备遥测或 WorkSpaces 服务，不显示捏造的延迟、带宽或实时健康度。网络状态只作示例，并在页脚标明。复杂诊断图表不塞入三台桌面的选择页。
+
+## 3. Omnissa Horizon：按资源设置与连接流程
+
+- 官方指南：https://docs.omnissa.com/HorizonClient-WindowsGuide-V2609/ConnecttoaRemoteDesktoporPublishedApplicationfromHorizonWindowsClient
+
+已核对官方流程文字：登录后进入桌面与应用选择器；可在桌面资源上打开 Settings 调整显示；连接以具体资源为单位。本文仅作为操作流程依据，没有将其称为已取得的界面截图。
+
+采用：每台桌面独立“设置”和“连接”；返回列表不退出账号；未配置地址时解释原因并保留设置入口。
+
+## 4. 与本仓库代码的对应
+
+- `terminal/kiosk-shell/src/desktop_list_page.cpp`：每张卡片都有“设置”，可用桌面有“连接”，忙碌时禁止重复操作。
+- `terminal/kiosk-shell/src/desktop_settings_dialog.cpp`：服务器地址、应用名、分辨率、帧率；地址留空表示未分配，桌面不可连接。
+- 原型的配置字段与上述真实代码对应；不增加没有来源的 CPU、内存、显卡容量或实时质量指标。
+
+## 5. 保留的视觉系统与可读性规则
+
+- 登录界面的 Logo、互动图形和深浅色视觉沿用原稿。后续按要求补充表单校验、登录状态、企业连接、SSO 和离线体验；相关浏览器验证见 `../output/playwright/login-verification.json`。
+- 登录后沿用深蓝灰背景、铜橙色强调、圆角卡片与低对比边框；去掉整块浅蓝、浅绿色带。
+- 系统识别只占卡片左上角：Windows 窗格图形、Ubuntu 官方形态图形、麒麟软件官方品牌图片，加明确的系统名称。色彩局部使用，连接按钮统一铜橙。
+- Ubuntu 图形来自 Simple Icons 的 Ubuntu 资源：https://raw.githubusercontent.com/simple-icons/simple-icons/develop/icons/ubuntu.svg 。
+- 麒麟软件图片直接来自官网：https://www.kylinos.cn/upload/1/appLogo/20250820/1957999505938382848.png 。该图是麒麟软件公司标识，不冒充单独的银河麒麟产品 Logo。
+- 主要桌面名称 22–24 px；正文和操作 14–16 px；辅助规格和设备状态 13 px。小字号正文按 WCAG AA 4.5:1 校验；大字号至少 3:1。
+- 常用操作至少 44 px 高，有文字标签；收藏按钮同时提供名称与选中状态；不可连接状态同时提供原因。
+- 深色、浅色、1280×720 / 1366×768 / 1920×1080 都独立渲染；不将“语法检查通过”等同于视觉验收。
+
+## 6. 交付边界
+
+这是 `ui/terminal` 下的 HTML 交互设计原型；连接配置保存在当前浏览器的本地存储供评审使用。真实终端认证、Moonlight 会话、设备遥测和 Qt 落地仍由 kiosk-shell 接入。原型不伪装远程连接成功，连接状态在预览等待后进入说明页，并提供检查设置的恢复路径。
