Multiplayer setup moves out of a canvas modal and a prompt() dialog into one
menu screen: your name, the two ways to host, and the friend's code. The socket
opens from the menu and the game stays parked behind the overlay until the room
fills — netHooks.paired takes the court one line before netStart writes to it —
so the room code can carry a real SHARE button and a wrong code is a typo you
fix rather than a CONNECTION LOST card over a match that never began.
The name is the world board's name (stats.saveName), crosses on the existing
look message, and the scoreboard finally names the person instead of CPU.
