MUST BE USED when user mentions Steam launch options, modifying shortcuts.vdf, Proton environment variables (PROTON_*, WINE*), Battle.net/Blizzard games on Linux, or RTX 4000+ performance fixes. ALSO USE when troubleshooting Proton/Wine game issues (black screen, game won't launch, launcher issues, CEF/Chromium rendering problems).
