// Minimal native stand-in for Arduino's Stream class. src/Utils.h includes
// <Stream.h> directly (mesh::Utils::printHex(Stream&, ...)), and
// src/Identity.cpp's readFrom/writeTo/printTo take a Stream& -- both real
// hardware File objects (fs::File, Adafruit_LittleFS's File) and our own
// SimFile (variants/sim/SimFS.h) derive from this, exactly like on real
// boards.
