openai/gpt-chat-latest → B (100:1)

Commit B introduces substantial new functionality and infrastructure: a complete pairwise voting UI, pair selection algorithms, dynamic UI morphing, item ID normalization improvements, integration and browser tests, reusable mock Reddit test support, CSS/JS updates, and related API changes. It spans many files and adds significant user-facing behavior and core logic. Commit A only removes a single test that produced a warning, with negligible impact on project functionality.
