Air mail with streamed JSX

A bush plane delivers mail across a landscape that the server and the browser render together with jsx-async-runtime. The server renders mountains, forests, lakes, villages and airstrips as JSX and streams them chunk by chunk over a single response while you fly. Thanks to backpressure, it only renders the next chunk when your browser reads on. Meanwhile the browser renders the sky, the plane, the parcels and the instruments for every animation frame. The course changes every day and is the same for everyone.
