Side A implements substantive UI and behavior improvements: it adds pairwise vote counts to garden voting controls backed by a new helper and test, changes the pin HUD from a permalink into a functional unpin action via `POST /ui set_garden_pin clear:true`, updates styling, documentation, and browser tests to support the new behavior. Side B is a small layout fix that simply moves the view counter into the existing top navigation and adjusts CSS to prevent overlap with authentication links.
