    PageSpeed Insights uses a three-tier scoring system for Core Web Vitals:
    - **Good (Green)**: FCP ≤1.8s, LCP ≤2.5s, CLS ≤0.1, INP ≤200ms, TTFB ≤800ms.
    - **Needs Improvement (Yellow)**: FCP 1.8-3s, LCP 2.5-4s, CLS 0.1-0.25, INP 200-500ms, TTFB 800-1800ms.
    - **Poor (Red)**: Exceeds upper thresholds of "Needs Improvement."
