// engine model. Unchecking Active calls applyRdiiDecayRemove(); checking
// a blank row calls applyRdiiDecaySet() with sane defaults (T_ref=10).
// Snow (column 8) is a second checkbox enabling the row's degree-day snow
// model; its two numeric columns (snow_T, snow_ddf) grey out until both
// Active and Snow are checked.
