每次开头请叫我哥哥

请严格遵守ui设计规范，使用响应式布局设计，不要硬编码
请使用项目里面封装好的ui组件，如果没有请提醒我
## Project Overview

React Native + Expo mobile application built on **Ignite CLI boilerplate** (v11.4.0). Uses TypeScript, React Navigation 7, and NativeWind (Tailwind CSS).

## Common Commands

```bash
pnpm install                    # Install dependencies
pnpm run start                  # Start Expo dev client
pnpm run android                # Run on Android (expo run:android)
pnpm run ios                    # Run on iOS (expo run:ios)
pnpm run compile                # TypeScript type check (tsc --noEmit)
pnpm run lint                   # ESLint with auto-fix
pnpm run lint:check             # ESLint without fix
pnpm run test                   # Run Jest tests
pnpm run test:watch             # Run Jest in watch mode

# EAS Builds (requires expo-cli)
pnpm run build:ios:sim          # iOS simulator build
pnpm run build:android:sim      # Android emulator build
pnpm run prebuild:clean         # Regenerate native projects
```

## Architecture

### Directory Structure

- `app/` - Main application source
  - `components/` - 12个基础 UI 组件（详见下方组件列表）
  - `screens/` - Screen components connected to navigation
  - `screens/DemoShowroomScreen/demos/` - 组件演示页面（展示组件用法，非实际组件）
  - `navigators/` - React Navigation configuration (AppNavigator, DemoNavigator)
  - `context/` - React Context providers (AuthContext, ThemeContext, ToastContext)
  - `services/api/` - API layer using Apisauce (`authApi.ts` for auth, `index.ts` for base API)
  - `theme/` - Design tokens (colors, spacing, typography) and theme system
  - `i18n/` - Internationalization with i18next (8 languages: en, zh, ar, es, fr, hi, ja, ko)
  - `utils/` - Utilities including MMKV storage wrapper
  - `config/` - Environment-based configuration (dev/prod)
  - `devtools/` - Reactotron configuration

### Key Patterns

**State Management**: React Context + MMKV for persistence. No Redux.

**Theming**: Use `useAppTheme()` hook and `ThemedStyle<T>` pattern:
```typescript
const $container: ThemedStyle<ViewStyle> = ({ colors, spacing }) => ({
  backgroundColor: colors.background,
  padding: spacing.lg,
})
```

**Navigation**: Two-layer structure - AppStack (auth/main screens) and DemoNavigator (bottom tabs). Type-safe routes defined in `navigationTypes.ts`. Auth screens: AuthWelcome, Login, Register, ForgotPassword. Main screens: Welcome, Profile, Settings, Security, Theme, Language, About, etc.

**API Layer**: Singleton `Api` class in `services/api/index.ts` using Apisauce with typed responses.

**Styling**: NativeWind (Tailwind CSS) configured. Use `className` prop for Tailwind styles.

**Authentication**: `AuthContext` provides full auth flow with step-based state machines for login, register, and password reset. Supports email/password and Google Sign-In. Uses JWT tokens stored in MMKV.

## UI 设计规范

### 参考文件

| 类型 | 文件路径 | 说明 |
|------|----------|------|
| **设计令牌** | `app/theme/colors.ts` | 颜色系统（浅色主题） |
| | `app/theme/colorsDark.ts` | 颜色系统（深色主题） |
| | `app/theme/spacing.ts` | 间距系统 |
| | `app/theme/typography.ts` | 字体排版 |
| | `app/theme/styles.ts` | 全局样式（$styles.container 等） |
| **UI 参考页面** | `app/screens/DemoCommunityScreen.tsx` | **最佳参考** - 标准页面结构、ListItem 用法、Section 标题 |
| | `app/screens/WelcomeScreen.tsx` | useHeader hook 用法 |
| | `app/screens/ProfileScreen.tsx` | 设置页面、用户卡片 |
| **组件演示** | `app/screens/DemoShowroomScreen/demos/` | 所有组件的用法示例（类似 Storybook） |

### 设计令牌

**颜色语义**（定义在 `app/theme/colors.ts`）:
```typescript
text: palette.neutral800        // 主要文本
textDim: palette.neutral600     // 次要文本
background: palette.neutral200  // 屏幕背景
border: palette.neutral400      // 边框
tint: palette.primary500        // 主色调（按钮、链接）
separator: palette.neutral300   // 分隔线
error: palette.angry500         // 错误
```

**间距系统**（`app/theme/spacing.ts`）:
```typescript
xxxs: 2, xxs: 4, xs: 8, sm: 12, md: 16, lg: 24, xl: 32, xxl: 48, xxxl: 64
```

**字体大小**（`app/components/Text.tsx`）:
```typescript
xxl: 36, xl: 24, lg: 20, md: 18, sm: 16(默认), xs: 14, xxs: 12
```

### Header 使用规范

**必须使用 `useHeader` hook**，不要直接在 Screen 内部放置 `<Header>` 组件。

```typescript
// ✅ 正确写法
import { useHeader } from "@/utils/useHeader"

useHeader({
  title: translate("screenName:title"),
  leftIcon: "back",
  onLeftPress: () => navigation.goBack(),
}, [])

return (
  <Screen safeAreaEdges={["bottom"]} contentContainerStyle={[$styles.container, themed($container)]}>
    {/* 内容 */}
  </Screen>
)

const $container: ThemedStyle<ViewStyle> = ({ spacing }) => ({
  paddingTop: spacing.lg, // 覆盖 $styles.container 的 56px
})
```

**原因**: Header 组件默认添加顶部安全区域 padding，直接放在 Screen 内容中会导致 Header 上方出现额外空白。`useHeader` 通过 `navigation.setOptions()` 将 Header 设置为导航层的一部分。

### 容器间距规范

`$styles.container`（定义在 `app/theme/styles.ts`）:
```typescript
container: {
  paddingTop: spacing.lg + spacing.xl,  // = 56px（为无 Header 的 Tab 页面设计）
  paddingHorizontal: spacing.lg,        // = 24px
}
```

**使用 useHeader 的页面**需在 `$container` 中覆盖 paddingTop 为 `spacing.lg` (24px)。

**不要**在页面内容中再添加额外的 paddingTop 或 marginTop，避免重复间距。

### ListItem 使用规范

**参考**: `app/screens/DemoCommunityScreen.tsx`

**默认无分隔线**，保持简洁风格：
```typescript
<ListItem
  tx="setting:option1"
  leftIcon="settings"
  rightIcon="caretRight"
  onPress={handlePress}
/>
```

只有**连续列表项**需要视觉分隔时，才使用 `bottomSeparator`，且**最后一项不需要**:
```typescript
<ListItem text="Item 1" bottomSeparator />
<ListItem text="Item 2" bottomSeparator />
<ListItem text="Item 3" />
```

### Section 标题规范

**参考**: `app/screens/DemoCommunityScreen.tsx` 的 `$sectionTitle` 样式

使用 `preset="subheading"` 作为 section 标题:
```typescript
<Text preset="subheading" tx="section:title" style={themed($sectionTitle)} />

const $sectionTitle: ThemedStyle<TextStyle> = ({ spacing }) => ({
  marginTop: spacing.xxl,  // 48px
})
```

### 页面结构模板

**有 Header 的页面**（如设置、详情页）:
```typescript
import { useHeader } from "@/utils/useHeader"

export const ExampleScreen: FC<Props> = ({ navigation }) => {
  const { themed } = useAppTheme()

  useHeader({
    title: translate("exampleScreen:title"),
    leftIcon: "back",
    onLeftPress: () => navigation.goBack(),
  }, [])

  return (
    <Screen
      preset="scroll"
      safeAreaEdges={["bottom"]}
      contentContainerStyle={[$styles.container, themed($container)]}
    >
      {/* 内容 */}
    </Screen>
  )
}

const $container: ThemedStyle<ViewStyle> = ({ spacing }) => ({
  paddingTop: spacing.lg,
})
```

**无 Header 的 Tab 页面**（参考 `DemoCommunityScreen.tsx`）:
```typescript
export const ExampleTabScreen: FC<Props> = () => {
  const { themed } = useAppTheme()

  return (
    <Screen preset="scroll" contentContainerStyle={$styles.container}>
      <Text preset="heading" tx="screen:title" style={themed($title)} />
      <Text tx="screen:description" style={themed($description)} />

      <Text preset="subheading" tx="screen:section1" style={themed($sectionTitle)} />
      <ListItem ... />
      <ListItem ... />
    </Screen>
  )
}

const $title: ThemedStyle<TextStyle> = ({ spacing }) => ({
  marginBottom: spacing.sm,
})

const $description: ThemedStyle<TextStyle> = ({ spacing }) => ({
  marginBottom: spacing.lg,
})

const $sectionTitle: ThemedStyle<TextStyle> = ({ spacing }) => ({
  marginTop: spacing.xxl,
})
```

### 组件列表 (`app/components/`)

| 组件 | 用途 |
|------|------|
| `Screen.tsx` | 屏幕容器（SafeArea + 键盘适配 + 滚动） |
| `Header.tsx` | 页面头部导航栏 |
| `Card.tsx` | 卡片容器 |
| `TextField.tsx` | 文本输入框 |
| `Button.tsx` | 按钮（default/filled/reversed 预设） |
| `EmptyState.tsx` | 空状态占位 |
| `ListItem.tsx` | 列表项 |
| `Icon.tsx` | 图标 |
| `Text.tsx` | 文本（heading/subheading/bold 等预设） |
| `AutoImage.tsx` | 自适应图片 |
| `Toggle/` | 开关/复选框/单选框 |
| `Avatar.tsx` | 用户头像（使用 expo-image 缓存） |
| `Modal.tsx` | 模态框（bottom/center 预设） |
| `Dialog.tsx` | 对话框（确认/提示） |

**注意**: `screens/DemoShowroomScreen/demos/` 目录下的 `Demo*.tsx` 文件是组件**演示页面**，用于展示组件的各种用法和变体，类似 Storybook，不是实际组件。

### 自适应布局

**Screen 组件预设**:
- `preset="fixed"` - 固定布局，不可滚动
- `preset="scroll"` - 始终可滚动
- `preset="auto"` - 智能判断：内容超出屏幕时才启用滚动

**安全区域**: 使用 `useSafeAreaInsetsStyle` hook 处理刘海屏
```typescript
<Screen safeAreaEdges={["top", "bottom"]}>
  {/* 内容自动避开刘海和底部指示条 */}
</Screen>
```

**间距系统** (`app/theme/spacing.ts`):
```typescript
xxxs: 2, xxs: 4, xs: 8, sm: 12, md: 16, lg: 24, xl: 32, xxl: 48, xxxl: 64
```

**字体大小** (`app/components/Text.tsx`) - 固定像素值，无响应式:
```typescript
xxl: 36, xl: 24, lg: 20, md: 18, sm: 16(默认), xs: 14, xxs: 12
```

### Path Aliases

- `@/*` → `app/*`
- `@assets/*` → `assets/*`

## Import Restrictions (ESLint enforced)

- Use `Text`, `Button`, `TextInput` from `@/components`, not from `react-native`
- Use `SafeAreaView` from `react-native-safe-area-context`, not from `react-native`
- Import named exports from `react` (not `import React from 'react'`)

## Testing

Jest with Testing Library for React Native. Test files use `.test.ts(x)` suffix. Setup in `test/setup.ts`.

Run single test:
```bash
pnpm run test -- --testPathPattern="storage"
```

## Web Support

This app runs on web via Expo. Use `pnpm run start` and press `w` to open web. Note: React Navigation's `headerRight` may not work reliably on web - consider placing header elements directly inside Screen components if targeting web.
