## Summary **What is the goal of this PR?** Replace SFINAE std::enable_if_t with a C++20 `requires` clause for clearer constraint expression and better compiler diagnostics on mismatch. --- ### AI Usage While CrossPoint doesn't have restrictions on AI tools in contributing, please be transparent about their usage as it helps set the right context for reviewers. Did you use AI tools to help write this code? _**NO**_
