 - **Dynamic Configuration**: Use the `config()` function to easily specify data type constraints for various depths. The system prevents incompatible configurations.
 - **Data Ingestion**: With `add_data()`, you can add new variables dynamically while ensuring they meet the established type and depth requirements.
 - **Insightful Summaries**: The `summary()` method provides a quick, detailed overview of your data's types, depths, and more.
-- **Dynamic Access**: Use Pythonic `__getattr__` and `__setattr__` methods for on-the-fly variable access, with robust error handling.
