~x-ai/grok-latest → A (3:1)

A lands lasting infrastructure: cookie/server-rendered themes (with login cookie re-issue and POST /theme) plus correct private-room wire URLs via item_path_for_api_in_room/forum_thread_web_url threaded through RPC and accompanied by tests. B is real but narrower UX polish—vote counts on garden compare icons and turning the pin HUD into an unpin POST—valuable with tests, yet not as foundational as A’s product-wide path and theme design.
