openai/gpt-chat-latest → A (100:1)

Commit A introduces substantial new functionality and infrastructure. It adds a new vote comparison page, pair-selection algorithms, dynamic UI morphing after votes, item ID normalization improvements, integration and unit tests, CSS/JS updates, and refactors related request handling. These changes materially expand the project's capabilities and improve correctness. Commit B is a formatting/refactoring pass that reorganizes imports, wraps lines, and adjusts code layout without changing behavior. While useful for readability and consistency, it contributes far less to the project's functionality.
