;
; Two envs are provided:
;   - esp32dev        : classic ESP32 (what the current OLED prototype uses)
;   - esp32-s3        : target board per docs/hardware.md (Phase 2)
;
; Default is esp32dev because the current prototype wiring (VSPI pins
; CS=5, DC=16, RESET=17) targets the classic ESP32 module that Arthur
; currently has plugged into his laptop.
