; BikeAudio — 3-board relay (iPhone -> Board A sink -> I2S -> Boards B/C sources -> JBL + Cardo)
;
; One ESP32 cannot be an A2DP sink and source at once, and an A2DP source can
; reach only one speaker — so the work is split across three boards that share
; an I2S bus. See README.md for wiring and the flash order.
;
; Build all:        pio run
; Build one board:  pio run -e sink | -e source_jbl | -e source_cardo
;
; Common specs preserved from the original sketch: ESP32 Arduino core 2.0.x via
; espressif32 ~6.6.0, esp32dev, huge_app partition (BT stack), 115200 monitor.
