// ============================================================
// 计划员七个视口的真实数据 E2E（离线桩：payload 来自现场 world.json）
//
// 现场截图反馈（2026-09-16）：
//   1 已排产但「设备负荷」整屏"休" / 2 已排产甘特报"尚无排产版本"
//   3 方案对比"加载失败" / 4 版本对比全是内部字段名
//   5 绩效指标口径不清 / 6 时段计划"日产能 0 件"却显示超载
//   7 资源利用率整屏 0%
//
// 桩数据不是手写的：由 scripts/gen_planner_e2e_fixtures.py 调用同一批域函数
// 从现场 world.json 生成（只读，不写回项目）。未设置 E2E_PLANNER_FIXTURES 时整组跳过。
