Same controller: thermistor on ADC0 averaged over 1000 free-running conversions, 50 kHz fan PWM on OC0B, 115200 Bd console with the full command set, EEPROM temperature histogram, watchdog-reset path into the boot section. The Steinhart-Hart math and the libm log are gone — the Beta equation and the cubic fan curve are consteval-evaluated into flash tables; the firmware never does floating point. Byte-identical .text in both libavr modes. Legacy stays on master. Co-Authored-By: Claude <noreply@anthropic.com>
