C++ 20 Innovations: High-Performance Cross-Platform Architecture in C++

summary
Claims that C++20 concepts and constraints plus a disciplined inclusion layout and build-time tag let one codebase deliver both a portable common quaternion and per-ISA optimized variants (SSE/AVX, Neon, WebAssembly SIMD). Implementation uses expression templates, a single build macro to select platform headers, and per-feature headers so adding SSE2/SS3/AVX or Neon compiles only those files. A working prototype compiles everywhere, isolates platform changes, and yields ISA-specific speedups.
