; PlatformIO Project Configuration File
;
; Build targets:
;   production – serial off, light-sleep on (normal deployment)
;   debug      – serial + meter diag + state tracing (real meter, real data)
;   test       – synthetic meter data + payload codec self-test (no real meter needed)
;
; LoRa frequency and sender IDs are configured in include/config.h,
; NOT via build flags.  Change them there before building.
