The post page links previous_in_category and next_in_category (the Journal's opt-in scored related mode) as server-rendered links with the title in the anchor text when the Journal answers one, else the site-wide previous_post and next_post (postNeighbours). Types, a fixture post and expectation lines for both cases.
