Research direction

Start by reproducing the issue in the demo with version 3.11.2, enabling compression and the sandbox, then compare the original JPEG files with the sandbox outputs. Identify which JPEG cases become HEIF and what distinguishes them. Done means the format behavior is consistent with the expected output and the affected cases are covered by verification.
