MicrosoftARMAssembler/Divinity-Fortnite-Internal ? reverse-engineered prompt

Build me a C++ project that shows a custom in game overlay for a DirectX 11 or DirectX 12 app, with a clean rendering framework and a simple interface for drawing text, boxes, lines, and a few basic widgets.

I want it to feel like a lightweight internal tool, with the overlay rendered smoothly on top of the target app and a small demo screen that shows the framework working. Keep the code organized so it’s easy to extend later, and include a basic example of how the overlay would be used in a real project. If you need to check current docs for any DirectX or Windows API details, go ahead and look them up online.
