.SH ARCHITECTURE
The service is implemented as multiple C++ classes that inherit from QObject and include D-Bus interface definitions. Each class corresponds to a specific system component and exposes its methods through D-Bus.

The service uses dynamic library loading (dlopen/dlsym) to access underlying system information libraries, providing a flexible and modular architecture.
