Side A adds substantial new functionality: a complete `/vote` comparison page, pair-selection logic that prioritizes bridge comparisons across connected components, in-place UI morphing after votes, improved item ID normalization (`from_storage`) to avoid inconsistent Reddit paths, and accompanying integration/unit tests. Side B mainly refines an existing feature by renaming `/vote/compare` to `/vote`, removing the swap button, fixing delegate attribution handling, and preventing an undesirable fallback when too few sibling items exist; these are useful polish and correctness fixes but have much narrower long-term impact.
