ditpowuh/steam-idle-playtime — reverse-engineered prompt

Build me a simple C# console app that can passively add Steam playtime to games I choose. I want it to ask me how I want to sign in, either with my Steam username and password or by scanning a QR code, then handle Steam Guard if Steam asks for confirmation in the mobile app.

After login, have it ask for a JSON file path. That file should contain a queue of games with the Steam app ID, a target number of minutes, and the current progress in minutes. The app should idle one game at a time, keep counting up the progress, and when a game reaches its target it should move to the next one automatically.

Please make the prompts friendly and easy to follow since I am not very technical. It should work for one game or several games in order, and save updated progress so I can stop and resume later. If anything about Steam login has changed, look up the current docs online if you need to.
