Dev blog with fastest navigation possible.

Slow websites drive users away. Even well-optimized sites can suffer from sluggish navigation. Such behavior is often due to poor internet connections or server overload. Achieving consistently fast navigation is challenging. While optimizations like prefetching or AI-driven prerendering can improve the navigation experience, they are often inconsistent and resource-intensive. Optimistic navigation goes completely the opposite way and, instead of preloading, creates the illusion that content is already loaded.
