~x-ai/grok-latest → B (2:1)

B lands lasting core design: typed `$form:i32` holes, RecordVote `next` navigation, vote route/CTA, and the compare slider/UI plumbing that the product builds on. A is valuable polish (HUD unpin vs false permalink, edge vote counts, regression tests) but refinements on existing garden-pin behavior rather than new foundational capability.
