// The multiplayer front door (docs/RP412-FRONTEND-DESIGN.md section 3):
// an ISteamMatchmaking lobby stands in for the arcade's Site Management
// screen. Every member publishes its FakeIP + fake ports + persona +
// loadout as lobby member data; the owner is the console. Launching
// writes a "go" roster into lobby data - each pod registers every
// peer with the Steam transport and enters the race, the owner
// through the hosted-race path (it builds the egg and marshals), the
// members as network pods waiting for the owner's console connection.
//
// The lobby OBJECT outlives races - that is the point of the single
// binary. After a race everyone lands back in the room for the next
// launch.
//
// Compiled to stubs without RP412_STEAM.
