To improve Astro Lighthouse scores, inline critical CSS, optimize font loading, and enable build-time compression to target 95+ across mobile and desktop using deterministic config and safe defaults.

The best way to optimize LCP in Astro is applying non-blocking loading patterns and resource prioritization, which reduces payload weight and directly targets LCP improvements for high Lighthouse scores.

Yes, you need astro-critters to inline critical CSS in your Astro project, as the performance playbook specifically enforces workflows with astro-critters and @playform/compress to achieve measurable rendering improvements.

Build-time compression works with Astro by enabling @playform/compress during the build process, reducing large CSS and JS payloads to boost rendering performance and improve Time to Interactive metrics.

Astro sites can have poor LCP scores due to suboptimal font loading and large CSS payloads, but applying non-blocking loading patterns and inlining critical CSS resolves these rendering bottlenecks for better performance.

Yes, you can use @playform/compress with astro-critters in an Astro performance workflow, as the structured playbook enforces deterministic config for both integrations to safely achieve 95+ Lighthouse scores.
