Lighthouse CI for performance, SEO, accessibility

Run visual regression tests with Percy or Chromatic.
Verify page load under 3 seconds on 4G, Lighthouse performance score >= 80, and no console errors.
Check missing alt tags, color contrast, and keyboard navigation.
Output frontend-test-report.json with Lighthouse scores and pass/fail counts.
