TECHNICAL PLAYBOOK // 8 MIN READ

Every 100ms of latency above 1.2 seconds erodes conversion rates by up to 7%. Legacy page builders choke the main thread with megabytes of unused DOM wrappers and render-blocking scripts.

Full Site Editing + Native CSS Scroll Timelines

By pairing WordPress Full Site Editing (FSE) block architecture with compositor-driven CSS animations and strict token systems in theme.json, growth teams can launch high-converting landing pages in minutes without sacrificing 99+ Lighthouse performance scores.
