- Includes image optimization (AVIF/WebP selection, responsive markup, LCP prioritization) and font strategies (variable fonts, font-display swap, subsetting)
- Addresses runtime performance: layout thrashing prevention, debouncing, requestAnimationFrame, and list virtualization for large datasets
- Provides caching strategies (Cache-Control headers, service worker patterns) and third-party script management (async loading, interaction-based delays, facade patterns)
