  W5.x.x 验收发现 2 处仍糊:
  - 红框 1: 顶栏面包屑 工作台 > 数据看板(暗主题)
  - 红框 2: 主题切换弹窗 切换主题/科技蓝/.../自动持久化(暗主题)

  根因:
  1. W5.x.x 覆盖 EP 派生色时漏了 --el-popper-bg-color(EP 2.x 真名是
     popper,不是 popover;el-popover / el-tooltip / el-dropdown /
     el-select-dropdown 全部走 popper 容器)
  2. el-breadcrumb 内部选择器优先级高,scoped :root 重定向的
     --el-text-color-* 被它打回
  3. ThemePicker 弹窗被 teleport 出去,scoped 选择器穿透不了
     popper 容器

  修法:
  1. tokens.scss 增 6 个 --el-popper-* 系列变量
  2. AppLayout.vue 末尾增 :deep(.el-breadcrumb__inner) +
     :deep(.el-breadcrumb__separator) + !important
  3. ThemePicker.vue 末尾增 :deep(.el-popper.is-light) + 内部
     el-popper__arrow / el-popper__title + !important

  验证: 切到 暗夜黑 主题,4 项验收清单全过;切回 科技蓝/中国红/
  深空紫 无回归
