That density is a constant, namely

. di normalden(0)
.39894228

Whatever mean a normal has just shifts the distribution left or right,
so makes no difference to what the peak density is; hence without loss
of generality we can focus on mean 0.

Whatever SD a normal has, 0/SD is still 0.

Correct me if I'm wrong....
