; Enlarge the Arduino loop_task stack (framework default 4KB / 1024 words is too
; small for LittleFS file opens from loop(), which overflow it and corrupt adjacent
; heap). 2048 words = 8KB. Requires the framework's LOOP_STACK_SZ #define to be
; #ifndef-guarded (Adafruit_nRF52_Arduino) so this override is honoured.
