leonardo-spy/Jondo.Unity.WebClient ? reverse-engineered prompt

Build me a browser version of the Dofus 3 Unity client from this repo, so I can open it in a normal web browser and log in all the way through server selection, character selection, and entering the world.

It should connect to the JondoEmu emulator over WebSocket, keep the existing auth flow working, and play the menu music and UI sounds. Please make sure the WebGL build and local web server start cleanly, and that the app runs without errors through the full login flow.

If you can, also preserve the current theme switching and the asset bundle loading from the client data. Map rendering and character rendering are not finished yet, so don’t worry about those unless they’re already close. If something depends on current Unity or build docs, look them up online and use the latest steps.
