~x-ai/grok-latest → A (2:1)

A fixes lasting correctness: VOTE attribution via out-of-band delegate_opt instead of stuffing WEB_BROWSER_AGENT into DSL body text, and stops silently expanding the sibling pool to all items when <2 (returns None). B’s vote-count badges and pin-HUD→unpin are useful UX polish with tests/CSS, but they are affordance/work-surface changes rather than core behavior fixes, so A carries more durable design value despite similar surface area.
