 [^1]: The previous version injects Preact into the production build. However, this is no longer possible as it does not support React Server Components. While overall bundle size has increased to about 85kB, most of the content can be pre-rendered on the server side, resulting in a low first contentful paint and time to interactive. Using React throughtout also leads to more consistent behavior with external libraries and components.
