Detailed Description
A minimal, STL-free expected/result type for failable operations.
Modeled after std::expected (C++23) but with no STL dependencies, no exceptions, and no dynamic allocation. Suitable for freestanding and embedded targets.
Uses the library's own simple_type_traits.h for move/forward and a built-in placement new to avoid pulling in any standard headers.
