+## 核心思路
+
+- 应用启动优先读取本地默认启动配置 `assets/config/bootstrap.json`
+- 如配置了 `bootstrap_config_url`，会继续拉取远程启动配置，并使用缓存兜底
+- 如配置了 `upgrade_config_url`，首帧后异步检查版本更新
+- 启动配置与升级配置已拆分，不再共用同一个 JSON
+- 屏幕方向支持通过启动配置中的 `preferredOrientations` 控制
+
 ## 快速开始
 
-### 1. 运行已有品牌
+### 运行已有品牌
 
 ```bash
-cd apps/quanxue
+cd apps/aixue
 flutter run
 ```
 
-### 2. 生成新品牌
+也可以替换为：
 
 ```bash
-# 1) 在 flavors/ 下创建品牌配置
-cp flavors/quanxue.yaml flavors/新品牌.yaml
-# 2) 修改配置中的 app_name, application_id, app_key, theme, branding
-# 3) 准备品牌资源（参见下方规格要求）
-mkdir flavors/新品牌
-cp 你的图标.png flavors/新品牌/icon.png
-cp 你的前景图.png flavors/新品牌/icon_foreground.png
-cp 你的启动图.png flavors/新品牌/splash.png
-# 4) 运行生成脚本
-dart run tool/generate_app.dart 新品牌
+cd apps/test
+flutter run
+```
+
+```bash
+cd apps/yunxiao
+flutter run
+```
+
+### 生成或重建品牌应用
+
+```bash
+dart run tool/generate_app.dart aixue
+dart run tool/generate_app.dart test
+dart run tool/generate_app.dart yunxiao
 ```
 
 生成脚本会自动完成：
-- 创建 Flutter 应用 → `apps/新品牌/`
-- 添加 `web_shell_core` 依赖
-- 覆写 `MainActivity` 继承 `CoreShellActivity`
-- 更新 `AndroidManifest.xml` 应用名
-- 生成品牌入口 `main.dart`
-- 复制品牌资源到生成目录
-- 添加 `flutter_launcher_icons` / `flutter_native_splash` 依赖
-- 自动生成应用图标和启动页
 
-### 3. 品牌配置格式
+- 创建 Flutter Android 应用到 `apps/<品牌名>/`
+- 添加 `web_shell_core` 依赖
+- 修正 Android `namespace` 与 `applicationId`
+- 生成 `MainActivity` 并继承 `CoreShellActivity`
+- 生成品牌入口 `lib/main.dart`
+- 生成本地默认启动配置 `assets/config/bootstrap.json`
+- 复制品牌资源到 `assets/branding/`
+- 注册 `assets/branding/` 与 `assets/config/`
+- 生成 launcher icon 与 splash
+- 注入 Android 签名配置
+
+## Flavor 配置格式
+
+每个品牌在 `flavors/<品牌名>.yaml` 中维护配置。
 
 ```yaml
-app_name: "全学通"                          # 应用名
-application_id: "com.yuanxuan.quanxue"       # 包名
-app_key: "quanxue_prod"                     # 业务标识
+app_name: "全学通"
+application_id: "com.yuanxuan.quanxue"
+app_key: "quanxue_prod"
+default_url: "https://example.com/login"
+bootstrap_config_url: "https://example.com/bootstrap.json"
+upgrade_config_url: "https://example.com/upgrade.json"
+preferred_orientations:
+  - "portraitUp"
+  - "portraitDown"
 theme:
-  accent_color: "0xFF3ED37B"                # 主题色
-  bg_color: "0xFFFFFFFF"                    # 背景色
-  text_color: "0xFF1F2937"                  # 主文字色

+  bg_color: "0xFFFFFFFF"
+  text_color: "0xFF1F2937"
+  muted_text_color: "0xFF6B7280"
 branding:
-  icon: "icon.png"                          # 应用图标（相对于 flavors/<品牌>/）
-  icon_background: "#FFFFFF"                # 自适应图标背景色
-  icon_foreground: "icon_foreground.png"    # 自适应图标前景
-  splash: "splash.png"                      # 启动页图片
-  splash_color: "#FFFFFF"                   # 启动页背景色
+  icon: "icon.png"
+  icon_background: "#FFFFFF"
+  icon_foreground: "icon_foreground.png"
+  splash: "splash.png"
+  splash_color: "#FFFFFF"
 ```
 
-### 4. 品牌资源规格
+### 字段说明
+
+- `default_url`：生成到本地默认启动配置 `assets/config/bootstrap.json`
+- `bootstrap_config_url`：可选，远程启动配置地址；为空时不会写入 `main.dart`
+- `upgrade_config_url`：可选，远程升级配置地址；为空时不会写入 `main.dart`
+- `preferred_orientations`：首屏方向配置，支持：
+  - `portraitUp`
+  - `portraitDown`
+  - `landscapeLeft`
+  - `landscapeRight`
+
+## 生成后的入口形态
+
+生成器会把品牌入口写成统一模板：
+
+```dart
+runShellApp(
+  ShellEnvironment(
+    appName: '品牌名',
+    appKey: 'brand_key',
+    accentColor: const Color(0xFF3ED37B),
+    backgroundColor: const Color(0xFFFFFFFF),
+    textColor: const Color(0xFF1F2937),
+    mutedTextColor: const Color(0xFF6B7280),
+    splashImage: const AssetImage('assets/branding/splash.png'),
+    bootstrapConfigAsset: 'assets/config/bootstrap.json',
+    bootstrapConfigUrl: 'https://example.com/bootstrap.json',
+    upgradeConfigUrl: 'https://example.com/upgrade.json',
+  ),
+);
+```
+
+其中远程地址为空时，对应字段不会写入生成结果。
+
+## 本地默认启动配置格式
+
+生成器会自动生成 `assets/config/bootstrap.json`：
+
+```json
+{
+  "initialUrl": "https://example.com/login",
+  "preferredOrientations": [
+    "portraitUp",
+    "portraitDown"
+  ]
+}
+```
+
+## 品牌资源规格
 
 | 资源 | 文件名 | 最小尺寸 | 格式 | 说明 |
 |---|---|---|---|---|
-| 应用图标 | `icon.png` | 1024×1024 | PNG | 正方形，用于生成各尺寸 launcher icon |
-| 自适应图标前景 | `icon_foreground.png` | 1024×1024 | PNG (透明背景) | 主体内容需居中，四周留 **25% 安全区** |
-| 启动页图片 | `splash.png` | 1152×1152 | PNG | 用于生成 Android 12+ 和旧版启动页 |
+| 应用图标 | `icon.png` | 1024×1024 | PNG | 用于生成各尺寸 launcher icon |

+| 启动页图片 | `splash.png` | 1152×1152 | PNG | 用于生成 Android 12+ 与旧版启动页 |
 
-> **提示：** 资源文件放置在 `flavors/<品牌名>/` 目录下，`branding` 中的路径相对于此目录。如果省略 `branding` 段，脚本会跳过图标和启动页生成。
+品牌资源源文件放在 `flavors/<品牌名>/` 下，生成后会复制到 `apps/<品牌名>/assets/branding/`。
 
 ## 调试说明
 
-部分教育平板设备使用 `Ctrl+C` 结束 `flutter run` 后，旧进程可能留在后台影响 WebView 启动。
+部分教育平板设备在 `flutter run` 中断后，旧进程可能残留并影响 WebView 启动。
+
+推荐做法：
 
-**推荐做法：**
 - 调试结束时在 `flutter run` 控制台按 `q` 退出
-- 或使用调试脚本自动杀旧进程再启动：
+- 或使用：
 
 ```powershell

+## 配置分层
+
+### 启动配置
+
+启动配置负责影响首屏加载行为，当前拆成两层：
+
+1. 本地默认启动配置：`assets/config/bootstrap.json`
+2. 远程启动配置：`bootstrap_config_url`
+
+字段示例：
+
+```json
+{
+  "initialUrl": "https://example.com/login",
+  "preferredOrientations": ["portraitUp", "portraitDown"]
+}
+```
+
+### 升级配置
+
+升级配置仅用于版本检查，不参与首页地址解析，单独由 `upgrade_config_url` 拉取。
+
+字段示例：
+
+```json
+{
+  "versionName": "1.0.1",
+  "version": 101,
+  "isForce": 0,
+  "remark": "1. 修复已知问题",
+  "filePath": "https://example.com/app-release.apk",
+  "fileSize": 25000
+}
 ```
 
 ## 核心流程
 
 ### 1. 启动流程
 
-```
-main() → runShellApp(env)
-  → WidgetsFlutterBinding.ensureInitialized()
-  → 设置屏幕方向（竖屏锁定）
-  → 进入沉浸式模式
-  → runApp(ShellApp)
-    → Android? → WebShellPage（WebView 容器）
-    → 其他?   → UnsupportedPlatformPage（兜底页）
+```text
+main()
+  → runShellApp(env)
+    → WidgetsFlutterBinding.ensureInitialized()
+    → 读取本地默认启动配置 bootstrapConfigAsset
+    → 拉取远程启动配置 bootstrapConfigUrl（可选，失败走缓存）
+    → 合并 initialUrl / preferredOrientations
+    → setupConfigUrl(upgradeConfigUrl)
+    → _initializeUrls()
+    → SystemChrome.setPreferredOrientations(...)
+    → 进入沉浸式模式
+    → runApp(ShellApp)
+      → Android   → WebShellPage
+      → 非 Android → UnsupportedPlatformPage
 ```
 
 ### 2. WebView 启动与恢复
 
-```
+```text
 WebShellPage.initState()
   → 查询 Android WebView 信息（SDK / 包名 / 版本号）
   → 生成兼容性策略（renderModes / useWideViewPort / aggressiveRecovery）
-  → 创建 WebView（默认 texture 模式）
-  → 首帧就绪后加载初始 URL
-  → 启动看门狗计时器
-    → 超时? → 切换渲染模式（hybrid）→ 深度清理 → 自动重试
-    → 再超时? → 展示错误页 + 兼容性提示
+  → 创建 WebView
+  → 首帧后加载 _initialUrl
+  → 同时异步执行 checkVersion(context)
+  → 主帧成功 → 注入 Bridge
+  → 主帧失败 → 展示 ErrorOverlay，不再白屏
+  → 启动超时 → 切换渲染模式 / 深度清理 / 自动重试
 ```
 
 ### 3. JS Bridge 协议
 
-```
-H5 页面                    Flutter 壳
-  │                          │
-  │  AppShellChannel.        │
-  │  postMessage(JSON)       │
-  │ ──────────────────────→  │  解析 action + payload
-  │                          │  执行对应 handler
-  │  window.                 │
-  │  __appShellReceiveResponse│
-  │ ←────────────────────── │  返回 { requestId, success, data/error }
+```text

+| `showToast` | 展示 Toast |
+| `setStatusBar` | 设置状态栏样式 |
 
 ## 兼容性策略
 
 | 条件 | 渲染模式 | 恢复策略 |
 |---|---|---|
-| SDK ≥ 29 + WebView ≥ 113 | texture 优先 | 标准恢复 |
-| SDK ≤ 28 或 WebView < 113 | hybrid 优先 | 激进恢复（2 次重试） |
+| SDK ≥ 29 + 新版 WebView | texture 优先 | 标准恢复 |
+| SDK ≤ 28 或旧版 WebView | hybrid 优先 | 激进恢复 |
 | F136A 设备 | hybrid 优先 | 激进恢复 + 建议更新 WebView |
