openai/gpt-chat-latest → A (4:1)

Side A replaces a large, unreliable keystroke-driven autocomplete graph with a much simpler paste-and-go flow: it removes the complex parser/action system, introduces a focused URL parser returning subreddit names, redirects directly to the ranking page on success, and adds targeted parsing tests. Side B improves the vote-compare page with fullscreen layout, better edge-history ordering/display, and live preview updates after posting, but these are narrower UI enhancements compared with A's substantial simplification and reliability improvement.
