Keys are generic over value types, preventing type mismatches at compile time, as highlighted in the README's examples with strongly typed keys.

Automatically serializes and deserializes any Codable-conforming object, eliminating manual JSON handling for complex structs and enums.

Implemented in fewer than 100 lines of code, making it lightweight and easy to integrate without adding bloat to your project.

The has() method checks key existence without deserializing values, saving performance for large or nested objects as noted in the README.
