/**
 * 票 18（批次 5：装饰/纹理替换）专项断言面。
 *
 * 立场同 batch2-token-check.mjs：零依赖 Node 静态断言，不运行构建/dev/浏览器。
 * 覆盖四件可断言事实：
 *   [A] 资源化装饰：manifest 条目存在、文件可达、hash 一致、status=formal、有注册表与消费点
 *   [B] 无死装饰资源：运行时图标目录不再有未登记的装饰候选文件
 *   [C] 代码化装饰无散落主题色：四角切角 data-URI 不再内联色值、第二底色走 --bg-1
 *   [D] 消费方式合法：样式层不出现物理资产路径（经语义 key 注入），装饰不碰结构属性
