/**
 * T47 设备状态视觉特效与门控 纯逻辑检查（票 47；决策票 07 的 `## Answer`）。

 * 零依赖 node 断言脚本（约定见 t01-panel-catalog.mjs）。
 * 运行：node .scratch/cockpit-shell-panel-layout/verify/t47-device-effects.mjs
 *
 * **这是三层证据里的第 1 层**（领域纯逻辑）：映射唯一、未知不猜、门控与 30 台降级可断言。
 * 它**不能单独作为验收** —— 映射表对不等于画面在动；"真在跑"的证据在
 * `t47-device-effects-walkthrough.mjs` 的**跨帧快照**与真实帧差里（决策票 07 问题 7）。
