; Self-contained PlatformIO project for the AutoProvision example.

; Host boards are provided — pick one with -e:
;     pio run -e esp32-s3-devkitc-1 -t upload   # generic ESP32-S3 dev board
;     pio run -e xiao-esp32s3       -t upload   # Seeed XIAO ESP32-S3
;     pio run -e xiao-esp32c3       -t upload   # Seeed XIAO ESP32-C3
;     pio device monitor
;
; The radio region is set via build flags — the same LORA_* defines you'd use
; when compiling MeshCore firmware. The host UART pins differ per board because
; the XIAO does not break out GPIO17/18.
;
; The library is pulled from the repo root (two levels up) via a relative
; symlink dependency, so there's no copy of the source.
