astro-optimizer

Performance optimization toolkit for Astro SSG sites. Analyzes and applies optimizations including resource preloading (fonts, images, CSS), page prefetching, image loading strategies (lazy/eager, fetchpriority), and configuration improvements. Use when the user asks to optimize an Astro site, improve Astro performance, add preloading, configure prefetching, or speed up their Astro build. Handles both automatic safe optimizations and user-confirmed risky optimizations.
