~x-ai/grok-latest → B (2:5)

B adds a full feature path (new CopyGardenRank action, garden/copy.rs markdown rebuild + clipboard JsBuilder flow, UI hooks on ranking headings, unit/integration/browser coverage and agents.md notes), which is lasting product surface. A only turns an existing static 📌 into an unpin form reuse of set_garden_pin plus CSS/test tweaks—useful UX polish, but much narrower than B’s end-to-end capability.
