### 🚑 其他信息(Other Information)

Start by locating the card-farming startup flow and the existing Steam status or privacy integration in the SteamTools codebase. Confirm how startup options are applied, then verify that enabling card farming also enables Steam invisibility and that the behavior is covered by the relevant tests or manual startup checks.
