Weekly text diff: compare against the approved baseline

For a recurring review, keep last week's approved text and compare it with the new version. Label intentional changes before investigating the rest. Check dates, prices, links, and names with extra care, since a small substitution can matter more than a large paragraph rewrite. If formatting is normalized, know whether the tool hides whitespace or Unicode differences. Save the accepted baseline for the next cycle rather than comparing against an arbitrary draft.
