HTTP 103 Early Hints

Preload hints sent before the final response.

What HTTP 103 Early Hints means

103 Early Hints lets the server send preload hints (like `Link` headers for CSS or scripts) before the final response is ready, so the browser can start fetching critical resources sooner. The real response follows once the server has it.
