The G0IV stellar class reads slightly warm for the cold boreal character described, but the subgiant's low surface gravity means the habitable zone sits at greater orbital distance, producing longer seasons and lower average insolation than a main-sequence star of equivalent luminosity. The mismatch between star type and planetary temperature is deliberate and consistent with the established stellar data.
