~x-ai/grok-latest → A (3:1)

A lands core product surface: a full /vote compare page, bridge-first pair selection in pair.rs, in-place morph of edge history after record_vote, ItemId::from_storage normalization, and integration/browser coverage. B’s paste-and-go rewrite correctly deletes an unreliable ~1.8k-line keystroke graph and race workarounds, but that is a navigation UX simplification, not new ranking/voting capability of comparable lasting depth.
