A hardware-inspired, ultra-optimized Arcade Tetris engine written in modern C++20. Operates on a zero-sleep main loop, dynamic 1D-array bidirectional iteration, compile-time constexpr LUTs for O(1) rotation/collision handling, and a strict multi-stage FSM line-clearing completion routine. Eschews external engines and multithreading.
