When\n  provided without left/right, it picks the first unvoted pair from the\n  pool's children. When provided alongside left/right, it constrains\n  \"next pair\" navigation to siblings within the pool.\n- \"vote on children\" button appears on item pages with ≥2 children,\n  linking to /vote?pool=<item>.\n- Pool is threaded through VoteComparePost → success JS so in-page\n  morph after voting keeps the pool context for next-pair navigation.\n\nCo-Authored-By: Claude Sonnet 4.6
