**Publishing for multi-language consumption:**
```bash

**Multi-language Args requirements:**
- Use `pulumi.Input[T]` type hints for all properties
- Args class must have `__init__` with typed parameters
- Constructor must have `args` parameter with type annotation
- Use `Optional[Input[T]]` for optional properties
