// 记忆整理「调优」卡的**真实渲染**测试（切片 MEMPANEL / M4）。
//
// 它钉住三件**文案与呈现**的事（逻辑那一半见 memoryTidyTuning.test.ts）：
//   ① 7 个键都有中文标签 + 各自的兜底说明（「留空 ⇒ 跟随谁」）；
//   ② 热生效与否**如实**：`hot:false` 必须写「重启后端后生效」，绝不写成「已生效」；
//   ③ 坏值**就地报错**并拦住保存（后端那道 400 仍在，但不让主人白跑）。
//
// 跑法（与 MemoryTidyDryRunCard.render.test.ts 同）：
//
//   cd frontend/web \
//     && ./node_modules/.bin/esbuild src/admin/modules/MemoryTidyTuningCard.render.test.ts \
//          --bundle --platform=node --format=cjs \
//          --outfile=/tmp/cyrene-memory-tidy-tuning.render.test.cjs \
//     && node /tmp/cyrene-memory-tidy-tuning.render.test.cjs
//
// `tsc --noEmit` 会对本文件做类型检查，因此它只从项目内导入、不 import node:*。
