openai/gpt-chat-latest → B (4:1)

Side B delivers a substantial UI improvement by redesigning the voting and ontology CSS across both default and retro themes, adding clearer layouts, improved controls, keyboard focus-visible states, better button and form styling, and more polished vote-compare/history presentation. Side A is almost entirely Clippy-driven cleanup (pattern simplifications, minor API/style tweaks, a type alias, allowing dead code in test helpers, and adding one missing #[test]) with little functional impact beyond ensuring an existing test runs.
