~x-ai/grok-latest → A (2:1)

A fixes real behavioral bugs: out-of-band WEB_BROWSER_AGENT delegation (correct attribution instead of stuffing it into DSL text), and refusing next-pair suggestions when the sibling pool has fewer than 2 items instead of silently falling back to the entire item set. B’s min–max score gradient is a clear UX improvement over ordinal coloring, but it is presentational polish versus A’s correctness and routing fixes.
