~x-ai/grok-latest → B (2:3)

B fixes core vote-compare correctness: rank-row gradients scoped per group, slider polarity/winner mapping aligned with HUD semantics, and history bars replaced by the same center-anchored slider model, backed by polarity and ranking invariant tests. A is valuable UX polish (unpin via POST clear, pairwise vote counts on garden icons, docs/CSS/browser coverage) but is additive surface rather than repairing the ranking/vote visualization contract.
