Review Summary

Your implementation correctly fulfills all core functional requirements. The function signature matches exactly, case insensitivity works properly with .lower(), and all test cases pass as expected. The use of a loop instead of Python's built-in .count() method is a style preference rather than a functional issue—your code produces correct results. Consider using phrase.lower().count(letter.lower()) as a more idiomatic approach in the future, but this is optional. Great work on getting the logic right!
