It's a self-contained PlatformIO project (`platformio.ini` + `src/main.cpp`) with
an env per host board — a generic ESP32-S3 dev board and a Seeed **XIAO
ESP32-S3** (their host UART pins differ, since the XIAO doesn't break out
GPIO17/18). The region is set the same way you'd compile MeshCore firmware —
an env per host board — a generic ESP32-S3 dev board and the Seeed **XIAO
ESP32-S3** / **XIAO ESP32-C3**. Their host UART pins differ (the XIAOs don't break
out GPIO17/18), and the XIAOs have only native USB, so their envs route `Serial`
to USB-CDC (`ARDUINO_USB_CDC_ON_BOOT=1`) — without that you get no serial monitor. The region is set the same way you'd compile MeshCore firmware —
`LORA_FREQ` / `LORA_BW` / `LORA_SF` / `LORA_CR` / `LORA_TX_POWER` in
`platformio.ini`'s `build_flags` (916.575 MHz / 62.5 kHz / SF7 / CR4/8 / 20 dBm).
The code is plain Arduino C++, so you can rename `src/main.cpp` to
examples/AutoProvision/platformio.ini
