Review Summary

Thanks for the contribution. I've reviewed the tests, and while they correctly validate the API caching logic, it seems the file naming (route.theme-contrast.test.ts) and test suite description ('Theme Contrast') don't match the actual content of the tests. Since this PR is already closed, no action is needed, but please keep this in mind for future contributions.

Labels Applied:

• level:beginner: The PR adds isolated test cases for an existing API endpoint without structural modifications.
• type:testing: The primary purpose of this PR is to add unit tests.
• mentor:Aamod007
