// What every other module here writes a line to on its way out, so the recipe can count the
// stops that ran. A real application would have a logger; the shape is the same.
//
// It is a dependency of the modules that write to it, so the loader builds it first and
// unloads it last, which is exactly why their `stop` can still reach it.
