/**
|
||||
* /table-test 探针 v11 —— 最终确认（只读诊断，不改仓库代码）。
|
||||
*
|
||||
* 已有结论（v1~v10）：
|
||||
* · 静止 61fps；纵向 ~10-15fps；横向 ~18-28fps；编辑态纵向 ~8-11fps
|
||||
* · **同一份 DOM 的冻结克隆滚到 60fps** → 瓶颈在 JS 重渲染，不在 CSS/绘制
|
||||
* · LoAF：滚动帧 ~90% 时间挂在一个 user-callback（库的 rAF）
|
||||
* · 首次点击 = 全表列重建（1008 次 DOM 变更）→ 300-500ms
|
||||
*
|
||||
* 本版要拿下的最后几个数字（都用交替多轮取中位，避免单轮方差）：
|
||||
* ① 全部 editor 移除 vs 保留 → customCell 层占多少（纵向/横向）
|
||||
* ② 首次点击 / 换行点击 / 同格点击 的耗时与 DOM 变更量（含 thead 是否重建）
|
||||
* ③ 「保存明细」按钮（findFirstError 全表校验）在 1000 / 5000 行下的耗时
|
||||
* ④ errorCount 在 1000 / 5000 行的重算耗时 + 一次提交的端到端延迟
