Side A makes functional, user-visible improvements by stabilizing the vote HUD layout with fixed column sizing, preventing slider reflow, and updating the slider track to visually indicate the current winning side via a new data-winner attribute and JavaScript/CSS changes, with a corresponding test assertion. Side B only removes an apparently unused helper function and two CSS border declarations, a small cleanup with little demonstrated lasting impact.
