Landing Performance
Review runtime performance and save findings to audits/performance-audit.json. Update release/qa-scorecard.json with measured values when available.
Review Areas
- Lighthouse scores
- LCP, CLS, and INP
- image and font strategy
- JS bundle size and unused code
- render-blocking resources
- animation cost
Guardrails
- do not mark pass without measured evidence
- prioritize first-screen speed over decorative complexity
- if a fix hurts accessibility or CTA clarity, note the tradeoff explicitly
