## **🎨 Design System Components**

### **1. useOnboardingStyles Hook**
**Purpose**: Centralized styling for all onboarding components
**Benefits**: 
- ✅ Consistent styling across all steps
- ✅ Easy to maintain and update
- ✅ Theme-aware styling
- ✅ Reusable style objects

```typescript
// Usage in any step component
const styles = useOnboardingStyles();

// Apply consistent styling
<Box sx={styles.container}>
  <Typography sx={styles.headerTitle}>Title</Typography>
  <Button sx={styles.primaryButton}>Action</Button>
</Box>
```

### **2. onboardingUtils Functions**
**Purpose**: Shared utility functions for common operations
**Benefits**:
- ✅ DRY (Don't Repeat Yourself) principle
- ✅ Consistent validation logic
- ✅ Reusable animation utilities
- ✅ Standardized error handling

```typescript
// Validation utilities
const isValid = validateApiKey(key, 'openai');
const status = getKeyStatus(key, 'openai');

// Animation utilities
const delay = getAnimationDelay(index);
const direction = getSlideDirection(current, target);

// Form utilities
const isValid = isFormValid(formValues);
const progress = calculateProgress(current, total);
```

### **3. OnboardingStepLayout Component**
**Purpose**: Consistent layout structure for all steps
**Benefits**:
- ✅ Standardized header structure
- ✅ Consistent spacing and typography
- ✅ Reusable animations
- ✅ Flexible content area

```typescript
<OnboardingStepLayout
  icon={<Key />}
  title="Connect Your AI Services"
  subtitle="Add your API keys to enable AI-powered content creation"
>
  {/* Step-specific content */}
</OnboardingStepLayout>
```

### **4. OnboardingCard Component**
**Purpose**: Consistent card styling with status indicators
**Benefits**:
- ✅ Standardized card appearance
- ✅ Built-in status validation
- ✅ Consistent hover effects
- ✅ Reusable across all steps

```typescript
<OnboardingCard
  title="OpenAI API Key"
  icon={<Security />}
  status={getKeyStatus(key, 'openai')}
  saved={!!savedKeys.openai}
>
  <TextField value={key} onChange={handleChange} />
</OnboardingCard>
```

## **🔧 Implementation Guidelines**

### **1. Step Component Structure**
Every onboarding step should follow this structure:

```typescript
import { useOnboardingStyles } from './common/useOnboardingStyles';
import { relevantUtils } from './common/onboardingUtils';

const StepComponent: React.FC<StepProps> = ({ onContinue }) => {
  const styles = useOnboardingStyles();
  
  // State management
  const [formData, setFormData] = useState({});
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);
  
  // Validation
  const isValid = isFormValid(formData);
  
  // Event handlers
  const handleSave = async () => {
    // Implementation
  };
  
  return (
    <Fade in={true} timeout={500}>
      <Box sx={styles.container}>
        {/* Header */}
        <Box sx={styles.header}>
          <Zoom in={true} timeout={600}>
            {/* Header content */}
          </Zoom>
        </Box>
        
        {/* Form content */}
        <Box sx={{ display: 'flex', flexDirection: 'column', gap: 3 }}>
          {/* Cards and form elements */}
        </Box>
        
        {/* Alerts */}
        {/* Action buttons */}
        {/* Skip section */}
      </Box>
    </Fade>
  );
};
```

### **2. Styling Guidelines**
- **Use the styles hook**: Always use `useOnboardingStyles()` for styling
- **Consistent spacing**: Use the predefined spacing values
- **Theme integration**: Leverage Material-UI theme for colors
- **Responsive design**: Use the responsive breakpoints

### **3. Animation Guidelines**
- **Fade in**: Use `Fade` component for step transitions
- **Zoom effects**: Use `Zoom` for important elements
- **Slide transitions**: Use `Slide` for step navigation
- **Consistent timing**: Use predefined timeouts (300ms, 500ms, 700ms)

### **4. Validation Guidelines**
- **Real-time validation**: Use debounced validation for better UX
- **Visual feedback**: Show status chips and border colors
- **Error handling**: Use `formatErrorMessage` for consistent error messages
- **Form validation**: Use `isFormValid` for form completeness

## **📋 Component Checklist**

### **For Each Step Component**
- [ ] **Import design system**: Use `useOnboardingStyles` and relevant utilities
- [ ] **Consistent structure**: Follow the standard component structure
- [ ] **Proper animations**: Use `Fade`, `Zoom`, and `Slide` components
- [ ] **Form validation**: Implement real-time validation with visual feedback
- [ ] **Error handling**: Use `formatErrorMessage` for error display
- [ ] **Loading states**: Show loading indicators during async operations
- [ ] **Auto-save**: Implement auto-save functionality where appropriate
- [ ] **Skip options**: Provide skip functionality for optional steps
- [ ] **Help sections**: Include collapsible help content

## **📚 Usage Examples**

### **Creating a New Step**
```typescript
// 1. Import design system
import { useOnboardingStyles } from './common/useOnboardingStyles';
import { validateRequired, formatErrorMessage } from './common/onboardingUtils';

// 2. Use the styles hook
const styles = useOnboardingStyles();

// 3. Implement consistent structure
const NewStep: React.FC<StepProps> = ({ onContinue }) => {
  // State and logic
  return (
    <Fade in={true} timeout={500}>
      <Box sx={styles.container}>
        {/* Header */}
        {/* Content */}
        {/* Actions */}
      </Box>
    </Fade>
  );
};
```

### **Adding New Utilities**
```typescript
// Add to onboardingUtils.ts
export const validateEmail = (email: string): boolean => {
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  return emailRegex.test(email);
};

export const formatPhoneNumber = (phone: string): string => {
  // Implementation
};
```
