-/**
- * Visual QA — Web Tasks board capture (#1999)
- * Viewport 1440x810 · themes light+dark · mock data mode (board renders in
- * fixture mode only — real mode stays on the honest coming-soon state).
- *
- * Gate assertions (hard failures, not warnings):
- * - board surface renders with >=2 board-column group titles (SSOT chrome);
- * - awaiting-review marker present (mock pool has 待评审 tasks);
- * - horizontalOverflow === false (document and tasks main surface);
- * - zero approve/merge controls on the Hub-only web surface (fail-closed).
- *
- * Usage (from app/web):
- *   node scripts/visual-qa-tasks-board.mjs
- * Env:
- *   AGENTHUB_WEB_E2E_PORT (default 5174)
- *   WEB_QA_URL / AGENTHUB_WEB_QA_URL — skip vite spawn when set
