I know about preprocessor directives, and I’ve seen some of the files for things like the iostream file, so I know how to use the yvals_core.h file to make a custom std-namespace-based file. That should provide you enough information to be able to see the capabilities of what I’ve made.

It's an internal header of the MSVC standard library implementation.
https://github.com/microsoft/STL/blob/main/stl/inc/yvals_core.h
I think it defines their internal macros, approximately equivalent to
<bits/c++config.h> for libstdc++ or <__config> for libc++.
