Filter and Square Even Numbers

Practice Python list comprehensions as a concise and expressive way to process sequences. You will work with a list of integers and use a single list comprehension to both filter values based on a condition and transform them into the desired form, instead of writing multiple loops and temporary lists.

The task is to design a list comprehension that reads the input list, keeps only the elements that meet the required criteria, and applies the correct transformation before building the final result list. Focus on writing a clear, readable expression that makes the filtering condition and the transformation step easy to understand at a glance.
