+
 ## Project Architecture
 
-This is a **Taro 4 + Vue 3 + NutUI** WeChat mini-program template with built-in authentication, offline support, and weak network handling.
+This is a **Taro 4 + Vue 3 + NutUI** WeChat mini-program with built-in authentication and reusable navigation components.
 
 ### Technology Stack
-- **Framework**: Taro 4.x (multi-platform mini-program framework)
-- **UI**: Vue 3 + NutUI 4.x (JD.com's UI library)
-- **State Management**: Pinia
+- **Framework**: Taro 4.1.9 + Vue 3.3.0 + Composition API
+- **UI Library**: NutUI 4.3.13 (JD.com's UI library for Taro)
+- **State Management**: Pinia 3.0.3 + taro-plugin-pinia
 - **HTTP Client**: axios-miniprogram
-- **Styling**: Less + TailwindCSS (dual design width system)
+- **Styling**: Less + TailwindCSS 3.x (dual design width system)
 - **Build Tool**: Webpack 5
+- **Navigation**: Custom TabBar + enhanced navigation hooks
 
 ### Dual Design Width System
 The project uses **two different design widths** configured in `config/index.js:16-23`:
 - **NutUI components**: 375px base width
 - **All other pages**: 750px base width
 
-When working with styles, always check if you're using NutUI components or custom components to determine which width to reference.
+When working with styles:
+- Check if you're using NutUI components → reference 375px designs
+- Custom page layouts → reference 750px designs
 
 ### Key Architectural Patterns
 
-#### 1. Authentication Flow (Required)
+#### 1. Reusable Navigation Components
+
+**TabBar Component** (`src/components/TabBar.vue`):
+- Fixed bottom navigation bar
+- Auto-adapts to safe areas (notch/home indicator)
+- Supports icon + text layout
+- Active state highlighting
+- Used across: Index, Mine, Family Office, Knowledge Base, Signing pages
+
+**NavHeader Component** (`src/components/NavHeader.vue`):
+- Custom navigation header with back button
+- Transparent/background variants
+- Safe area padding for notch devices
+- Replaces default Taro navigation bar
+
+**IconFont Component** (`src/components/IconFont.vue`):
+- Icon font wrapper for custom icons
+- Supports size and color customization
+
+#### 2. Authentication Flow (Required)
+
 The project has a sophisticated authentication system with automatic session management:
 
 **Startup Flow** (`src/app.js:26-214`):
 1. App saves launch path for auth callback
 2. Checks network status and handles weak network scenarios
 3. Attempts silent auth if not authenticated
-4. On auth success, enables offline booking cache polling
+4. On auth success, enables offline features
 
 **Core Files**:
 - `src/utils/authRedirect.js` - All auth logic (silent refresh, navigation, state)
 - `src/utils/request.js` - HTTP client with 401 auto-refresh interceptor
 - `src/pages/auth/index.vue` - Auth page (must be preserved)
+- `src/pages/login/index.vue` - Login page

-The app gracefully handles network issues through multiple mechanisms:
-
-**Network Detection** (`src/utils/network.js`):
-- Monitors network status changes
-- Detects weak network conditions
-- Provides offline caching capabilities
-
-**Offline Booking Cache** (`src/composables/useOfflineBookingCache.js`):
-- Caches booking data for offline access
-- Supports reading/writing cached data
-- Used when network is unavailable
-
-**Cache Polling** (`src/composables/useOfflineBookingCachePolling.js`):
-- Background polling to refresh cached data
-- Reference-counted enable/disable mechanism
-- Only runs when network is available
-
-**Weak Network UI** (`src/utils/uiText.js`):
-- Centralized copy management for weak network scenarios
-- Provides modal options for user interaction
-
-**Fallback Flow** (`src/utils/request.js:143-168`):
-1. Request times out or fails
-2. Checks if offline cache exists
-3. If yes, redirects to offline booking list
-4. If no, shows weak network modal

+### Styling Guidelines
+
+**When to use TailwindCSS** (80% of cases):
+```vue
+<div class="flex items-center justify-between p-4 bg-white">
+  <h1 class="text-xl font-bold text-gray-900">Title</h1>
+</div>

+- Deep selectors (`:deep()`)
+- Animations and transitions
+- Pseudo-elements (`::before`, `::after`)
+```less
+<style lang="less" scoped>
+.custom-card {
+  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
+  border-radius: 16px;

+
+## Development Workflow
+
+### Adding New Pages
+
+1. **Create page directory**:
+   ```bash
+   src/pages/your-page/
+   ├── index.vue
+   └── index.config.js
+   ```
+
+2. **Configure page** (`index.config.js`):
+   ```javascript
+   export default {
+     navigationBarTitleText: 'Your Page Title',
+     enablePullDownRefresh: true,
+     backgroundColor: '#f5f5f5'
+   }
+   ```
+
+3. **Register route** in `src/app.config.js`:
+   ```javascript
+   pages: [
+     'pages/your-page/index',
+     // ...
+   ]
+   ```
+
+4. **Use composition API** in `index.vue`:
+   ```vue
+   <script setup>
+   import { ref, onMounted } from 'vue'
+   import { useLoad, useShow } from '@tarojs/taro'
+
+   useLoad((options) => {
+     console.log('Page loaded with options:', options)
+   })
+
+   // Your component logic
+   </script>
+   ```
+
+5. **Add navigation** (optional TabBar integration):
+   - Import and use `TabBar` component
+   - Configure active state based on route
+
+### Adding API Calls
+
+1. **Define API** in `src/api/index.js`:
+   ```javascript
+   export const getProductListAPI = (params) => {
+       return buildApiUrl('product_list', params)
+   }
+   ```
+
+2. **Use in page**:
+   ```javascript
+   import { getProductListAPI } from '@/api'
+   import { fn } from '@/api/fn'
+
+   const fetchProducts = async () => {
+     try {
+       const res = await fn(getProductListAPI({ page: 1 }))
+       if (res.code === 1) {
+         products.value = res.data
+       }
+     } catch (err) {
+       console.error('Failed to fetch products:', err)
+     }
+   }
+   ```
+
+### Using Navigation
+
+**Recommended**: Use `useGo` hook for enhanced navigation:
+```javascript
+import { useGo } from '@/hooks/useGo'
+
+const go = useGo()
+
+// Navigate to page
+go('/pages/detail/index')
+
+// Navigate with params
+go('/pages/detail/index', { id: 123 })
+
+// Go back
+go.back()
+```
+
+**Alternative**: Use Taro's built-in navigation:
+```javascript
+import Taro from '@tarojs/taro'
+
+Taro.navigateTo({
+  url: '/pages/detail/index?id=123'
+})
+```
+
+### State Management with Pinia
+
+**Create store** (`src/stores/yourStore.js`):
+```javascript
+import { defineStore } from 'pinia'
+import { ref } from 'vue'
+
+export const useYourStore = defineStore('yourStore', () => {
+  const state = ref(null)
+
+  function setState(newState) {
+    state.value = newState
+  }
+
+  return { state, setState }
+})
+```
+
+**Use in component**:
+```javascript
+import { useYourStore } from '@/stores/yourStore'
+
+const store = useYourStore()
+store.setState('new value')
+```

+
+## Debugging Tips
+
+When debugging issues:
+
+1. **Check environment config**:
+   - Verify `BASE_URL` in `src/utils/config.js`
+   - Check business module identifier `f` and `client_name`
+
+2. **Verify authentication**:
+   - Check `sessionid` in localStorage
+   - Enable verbose logging in `src/utils/request.js` interceptor
+   - Test 401 refresh flow
+
+3. **Network issues**:
+   - Use Taro's built-in network status monitoring
+   - Check weak network fallback scenarios
+   - Verify offline cache interactions
+
+4. **Styling problems**:
+   - Confirm design width (375px vs 750px)
+   - Check if NutUI component or custom component
+   - Verify TailwindCSS classes are applied
+
+5. **Navigation issues**:
+   - Check route is registered in `src/app.config.js`
+   - Verify page directory structure matches route
+   - Use `useGo` hook for consistent navigation
+
+## Best Practices
+
+### Component Development
+- Use `<script setup>` syntax
+- Composables for reusable logic
+- Props should have type definitions
+- Use `emit` for child-to-parent communication
+- Prefer TailwindCSS for styling
+
+### API Integration
+- Always check `res.code === 1` for success
+- Use `try/catch` for error handling
+- Show loading states during requests
+- Handle network errors gracefully
+
+### Performance
+- Use page lazy loading (subpackages)
+- Optimize images with CDN parameters
+- Avoid large data sets without pagination
+- Clean up timers and listeners in `onUnmounted`
+
+### Code Style
+- Follow Vue 3 Composition API patterns
+- Use descriptive variable names
+- Keep functions focused and small (< 50 lines)
+- Add JSDoc comments for complex functions
+- Run `pnpm lint` before committing
