+; Native build for macOS (Darwin / arm64 + x86_64). Headless meshtasticd that
+; runs in SimRadio mode (`-s`) or against real LoRa hardware via a CH341
+; USB-SPI bridge. No BlueZ, libgpiod, or Linux I2C — those require Linux.
+;
+; Prerequisites (Homebrew):
+;   brew install platformio yaml-cpp libuv openssl@3 libusb argp-standalone pkg-config
+;
+; The macOS-side patches now live upstream:
+;   * meshtastic/platform-native — `String.h`-shadow shim, `-Wno-enum-constexpr-conversion`,
+;     empty-variant-dir guard. Pulled via `portduino_base.platform` zip pin.
+;   * meshtastic/framework-portduino — LinuxHardwareI2C macOS stubs, AsyncUDP
+;     SOCK_NONBLOCK fallback, Common.h __APPLE__ guard, WiFiServer.cpp extern-C
+;     fix, package.json URL refresh. Pulled by platform-native at its pinned commit.
+; This env therefore only carries the firmware-side build flags and src filter.
