Lighthouse Scores
For every site theme section you design or change, run Lighthouse on a representative live page after publication. Keep the Performance score at 90 or above and Accessibility, Best Practices, and SEO at 100. Fix any regression before completing the work. If a required score cannot be reached, notify an administrator with the measured scores and unresolved findings.
Fix
Audit the affected live pages with Lighthouse, resolve the reported issues, publish the corrected section, and verify the scores again. Notify an administrator when a required score remains below its threshold.
