A adds a real missing interaction (unpin directly from ranked child rows via the same POST /ui flow) with corresponding CSS states and an extended browser test covering the new UX path, delivering tangible user-facing functionality. B is a reasonable visual tweak (min-max score gradient) with good unit tests, but it's a smaller, purely cosmetic refinement affecting only color mapping, with lower functional impact than A's new capability.
