Browser-test coverage the reviewer asked for on the step 36 batch: the
year, menu-button and list-option state layer/focus ring (with the
option's ring drawn inset in its row), a selected day's hover layer
over its primary fill versus none on a disabled or blank day, and the
40px day indicator holding its size at a 20px root font size while
only its (rem-sized) text grows.
