openai/gpt-chat-latest → A (4:1)

Side A makes a substantive storage-model redesign by replacing the durable recent-vote deque with an append-only list, removing post-commit trimming, updating schema versioning, capping history at query time, and adding a focused regression test to verify only the newest 200 votes are loaded. Side B mostly adds UI features (vote page plumbing, typed form holes, navigation, CSS/JS, and dependencies), but despite its size it contains comparatively less core architectural value than A's persistence and data-loading changes.
