I rebuilt the classic Cactus Kev poker hand evaluator from scratch in modern C# (.NET 8), focusing on algorithmic clarity and performance instead of lookup tables.

• Pure C#, no unsafe code • Evaluates ~115 million 7-card hands per second • Uses Span<T> and BenchmarkDotNet • Detailed benchmarks and architecture in the README
