Functions
double	fsw::calibration::rtd::temp_to_resistance_cvd (double t_c, const CVDCoeffs &cvd=CVDCoeffs{})
	Resistance (Ω) at temperature (°C), IEC 60751 Callendar-Van Dusen, the C term below 0 °C.
double	fsw::calibration::rtd::resistance_to_temp_cvd_full (double resistance_ohms, const CVDCoeffs &cvd=CVDCoeffs{})
	The full CVD inverse: exact above 0 °C (the quadratic), Newton on the C term below it.
double	fsw::calibration::rtd::rtd_board_adc_to_temp_c (int32_t adc_raw, double adc_ref_voltage, double excitation_ua, double r0_ohms)
	An ESP32 RTD board's reading -> °C: the ADC code (2^31 = adc_ref_voltage) is the voltage across the element carrying excitation_ua, so R = V / I, then the full CVD inverse.
double	fsw::calibration::rtd::resistance_to_temp_cvd (double resistance_ohms, const CVDCoeffs &cvd=CVDCoeffs{})
	Convert resistance (Ω) to temperature (°C) using iterative CVD inverse.
double	fsw::calibration::rtd::counts_to_resistance (int32_t counts, double gain, double offset)
	Convert ADC counts to resistance (assuming linear relationship).
std::vector< double >	fsw::calibration::tc::nist_type_k_mv_to_c ()
	NIST ITS-90 Type K coefficients (0–1372 °C range, voltage in mV → temp in °C) Simplified 9th-order from NIST tables.
