 * @brief Example sketch demonstrating the Modest IoT Nano-framework (C++ Edition).
 * 
 * Implements an interrupt-driven LED toggle using the ToggableLedDevice class, showcasing the framework’s
 * event-driven and CQRS-inspired design. Requires the framework from
 * https://github.com/avelasquezn/Modest-IoT-Nano-framework-Cpp.
