Let me introduce you to the Carbonyl web browser! Drawing There isn't much you can draw in a terminal, you're guaranteed to be able to render monospace characters in a fixed grid, and that's it.

Mojo receivers such as our service are part of the native handles we can send between processes, to register the implementation we just need to add it to the BrowserInterfaceBroker, which will get called by the renderer through BrowserInterfaceBrokerProxy:
