The lab score moved from 96 to 97. The noise band is ±5 points, so this is neither an improvement nor a regression. The report compares metric medians and closed rule states instead.

Performance · field (CrUX)

New site with too little traffic: no CrUX data at URL or origin level. The report shows lab data only and says so.
