And lo! By the ancient and not-especially-deserved contrib powers vested in me: The appropriate tag. (Since, y'know, it's getting pretty clear by now that it's merited.)
I've also removed the Office Workers tag (because they clearly aren't, her position in the opening chapter or two notwithstanding) and am debating the merits of a "supernatural" tag or some such to describe their wonky world, but that last one doesn't seem clear to me.
