01 / Bring both versions
What actually changed?
Start with a demo, or paste or open your HTML files.
02 / Review the evidence

Make the next review easier.
The receipt records both filenames, byte counts, every comparison view, existing and new reference clues, and your note. It includes the source diff, so treat it like the original files.
