Side B delivers more substantive functional value: a real vote-count feature (edge_vote_count_for_pair with unit test) surfaced in the UI, plus a genuine bugfix converting a dead pin-HUD link into a working unpin form with corresponding CSS and browser test coverage. Side A is a smaller cleanup (route rename, removing a button, out-of-band delegate) that is useful but narrower in scope and less tested/verified than B's changes.
