Google C++ Style Guide

Official Google C++ coding standards for consistent, maintainable code.

Golden Rules

1. Target C++20 — avoid non-standard extensions
2. 80-character line limit — for readability
3. 2-space indentation — no tabs
4. Use const liberally — for correctness and thread safety
5. Avoid exceptions — Google code doesn't use C++ exceptions
6. Smart pointers for ownership — std::unique_ptr and std::shared_ptr
7. Header guards — use PROJECT_PATH_FILE_H_ format
