Ordered factors use orthogonal polynomial contrasts by default. The .L and
.Q stand for the linear and quadratic terms. Unordered factors use
"treatment" contrasts although (they're actually not contrasts), that are
interpreted as you described.
If you do not know what this means, you need to do s

Within rounding error, you got the right intercept, log(3); slope, 0;
