openai/gpt-chat-latest → B (5:1)

Side B fixes a concrete UI correctness issue by making vote highlighting and history consistently reflect the winning side, adds helper functions for winner/slider mapping, updates CSS/JS accordingly, and backs the behavior with targeted unit tests covering ratio orientation and ranking polarity. Side A is primarily a large CLI/documentation reshaping and command reorganization with corresponding test updates, which improves interface consistency but is mostly structural rather than introducing a comparably durable functional fix.
