Improved API Documentation

The API maintained documentation from doxygen isn’t very descriptive, mainly just listing the functions and classes. Would it be worth adding more detailed doxygen documentation? Perhaps in a separate file if the reason is code bloat.

Review the current Doxygen-generated API documentation and the repository's Doxygen setup, then determine which public functions and classes need more descriptive guidance. Clarify whether the additions should live in source comments or a separate file; done means the API documentation is meaningfully more descriptive without unacceptable code bloat.
