/**
 * 🔴 层级约定(2026-08-03,踩坑后定):**浮层 z ≥ 70,模态 z ≥ 80**。
 *
 * 助手窗是 `fixed z-[60]`(pet fab 61、数据流粒子 62)。shadcn 默认给浮层 `z-50` ——
 * 于是**任何在助手窗里打开的浮层都渲染在它底下**:
 *   · Select/Popover 类:点了有反应(DOM 里 listbox 确实打开),但一个选项都看不见;
 *   · Dialog/AlertDialog 类更糟:Radix 会给 body 设 `pointer-events:none`,
 *     弹窗看不见、整页却已经被锁住 —— 用户看到的就是**卡死**。
 * ⚠️ 这类错**不报任何错**,只能实测发现。⛔ 别把 z 调回 50。
