What was done

• [fixed] MED the placard said "Running it needs the repository around it", false (the check runs from an empty folder): cc79bde660 removed the sentence and the source-mirror sweep of 2026-09-27 (8ff502a104) regenerated the placard, which now says it runs from the files this site serves, but not identically to the repository's run.
• [fixed] MINOR "Floor 120 million years old (median)" where the data give 120.58: now 121, matching the page's P2 note (f2eba39310).
