openai/gpt-5.2-chat → B (1:5)

Side B delivers a substantial UI and correctness improvement: fixes vote compare highlighting, rewrites slider polarity logic, adds winner semantics, updates CSS rendering for center-anchored gradients, adjusts JS behavior, removes obsolete code, and introduces multiple focused tests including an end-to-end ranking invariant. It spans several modules (HTML, CSS, JS) with meaningful behavioral impact. Side A is a small cleanup removing dead code and adjusting a single test expectation. Therefore, Side B contributes significantly more overall value.
