Am I right in reading this as a 16-wide array stored in a vector that's either
zero-lengthed or one (given that on initialization we add a single element to
the vector)? I feel there must be a better pattern than storing an array in a
vector -- a potentially empty unique_ptr to a std::array, and allocate the
array off the heap when it's needed?
