openai/gpt-chat-latest → B (3:2)

Side B adds a meaningful user-facing capability by turning the ranked child-group pin indicator into a working unpin control that reuses the existing POST /ui set_garden_pin flow, updates rendering to preserve navigation, adjusts styling, and extends browser integration tests to verify the full interaction. Side A is a solid import bugfix that filters stickied/pinned Reddit posts during subreddit listing import and adds unit tests, but its scope is narrower than the end-to-end UI functionality and coverage added in Side B.
