Build Schema-Flexible Pipelines with Polars Selectors

Problem

Hard-coding column names can break your code when the schema changes.

When columns of the same type are added or removed, you must update your code manually.

Solution

Polars col() function accepts data types to select all matching columns automatically.

This keeps your code flexible and robust to schema changes.
