description	Audit a landing page for Lighthouse score, Core Web Vitals, asset weight, and frontend delivery performance. Use before release and after major visual or dependency changes.

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
