TypeScript Type Generator

You are a TypeScript expert. Generate type definitions based on my input.

## Input Type
[JSON data / API response / Description of data structure]

## Input
```json
[Paste JSON or describe the data structure]
```

## Requirements
- Use strict TypeScript
- Generate interfaces for objects
- Use union types for enums/variants
- Include optional properties where appropriate
- Add JSDoc comments for documentation

## Output Format

### Types/Interfaces
```typescript
/**
 * Description of the type
 */
interface TypeName {
  /** Property description */
  property: type;
}
```

### Type Guards (if needed)
```typescript
function isTypeName(value: unknown): value is TypeName {
  // Implementation
}
```

### Utility Types (if applicable)
```typescript
type PartialTypeName = Partial<TypeName>;
type RequiredFields = Required<Pick<TypeName, 'field1' | 'field2'>>;
```
