/**
 * @brief Arduino-compatible Print base class stub for native builds.
 *
 * This class provides a minimal interface compatible with the Arduino Print class,
 * allowing code that uses Print (and derived classes like Serial, Stream, etc.)
 * to compile and run on non-Arduino (desktop/native) platforms.
 *
 * Methods such as write(), print(), and println() mimic the Arduino API, enabling
 * easy porting and testing of Arduino libraries and sketches in a standard C++ environment.
 *
 * To use, derive from Print and implement the write(uint8_t) method to define how
 * output is handled (e.g., to std::cout, a file, or a buffer).
