~x-ai/grok-latest → B (2:1)

B redesigns the core recent-votes path (Deque/VecDeque → append-only List/Vec, schema v3→v4, drop write-time trim in projection_apply, cap only on load) with a dedicated unit test—lasting storage/reducer simplification. A is a solid but narrower UX win: wiring the existing set_garden_pin clear POST into ranked child pin icons plus CSS and browser coverage.
