MicrosoftMacroAssembler/Popstar-Fortnite-External — reverse-engineered prompt

Build me a Windows C++ overlay app inspired by this Fortnite external source. I mainly want the interface and visualization parts working, with a clean menu, quick bar, interactive leaderboard panel, item and object display for pickups, containers, supply drops, and buildings, plus smooth cached updates so it feels fast even on weaker PCs.

Please keep it as a private educational demo and don’t add anything for bypassing anti cheat, harming other players, or abusing live matches. If any game data access is unsafe or not available, stub it with mock data so the UI and rendering still work. Make it easy to open in Visual Studio, build, run, and understand. Look up current docs online if you need to.
