Side B delivers multiple functional improvements: it adds pairwise vote counts to garden compare links via a new `edge_vote_count_for_pair` helper, changes the pinned-item HUD into an in-place unpin action (`POST /ui set_garden_pin clear`), updates styling, and adds both unit and browser tests to verify the behavior. Side A is a useful but narrower CLI enhancement that formats and displays existing connectivity statistics with tests, exposing data already available rather than adding comparable new interaction or functionality.
