~x-ai/grok-latest → A (3:1)

A fixes real ranking/vote-display bugs (per-group gradient ordinals instead of global offsets; center-anchored winner fill and slider polarity matching the HUD) and locks them in with polarity/unit tests, so the core compare UX stays correct. B only wires an existing unpin RPC onto ranked-child pin icons plus browser coverage—useful consistency, but a smaller localized feature than A’s correctness work.
