This is your go-to when you need modern C++ done right. It enforces C++ Core Guidelines, won't let you skip sanitizers, and pushes you toward concepts, RAII, and smart pointers instead of the old-school pitfalls. The workflow is practical: analyze your build setup, design with type safety, implement zero-cost abstractions, then verify with AddressSanitizer before you benchmark. It comes with reference guides for template metaprogramming, SIMD optimization, and CMake configuration. If you're refactoring legacy code to C++20/23 or building high-performance systems where every allocation matters, this keeps you honest about memory safety and performance without the usual hand-waving.
