They receive events from the [HttpServer](src/node_modules/http/http_server.mjs) via their `routeAsync()` methods, then turn around and call the appropriate methods on [HomePageController](src/www/home_page/home_page_controller.js) and [Rot13Controller](src/rot13_service/rot13_controller.js). However, because the pattern is spread across multiple classes, it's not very clear in the code.
