Complete the page description.
The frontmatter description ends with "which contains a". The following text is outside the frontmatter, so generated metadata remains incomplete. Put the full sentence in description and remove or relocate the body fragment.

Preserve response bytes before creating requests.Response.
build_fetch_script() decodes the body with response.text() at line 100. response_from_evaluated() then encodes that decoded text as UTF-8 at line 136. Non-UTF-8 bytes are replaced during decoding and cannot be recovered. This makes response.content incorrect and can corrupt response.text.
Serialize response.arrayBuffer() with a byte-preserving envelope. Assign the original bytes to requests.Response, and derive response.encoding from Content-Type instead of forcing UTF-8.
