openai/gpt-5.2-chat → A (20:1)

Side A performs a major refactor: removing a 1400+ line monolithic file and reorganizing the forum HTML into a well-structured module hierarchy (feed, views, paginator, profile, morph handlers, etc.), significantly improving maintainability and clarity. Side B is a trivial markup tweak (changing a disabled span to an anchor). The scale and impact of A vastly exceed B.
