  title: Unity Lobby Host and Query
  summary: Create a public lobby, send a keep-alive heartbeat, then confirm it is discoverable via query.
  description: >-
    The host side of the Unity Lobby matchmaking flow. The workflow creates a
    new public lobby with the requesting player as host, sends a heartbeat so
    the lobby stays active and is not garbage collected, and then queries
    available public lobbies to confirm the new lobby is discoverable by other
    players. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
