name	模板文本引擎
description	后台引擎：拦截文本 Wrap 逻辑，动态替换为 Template 数据。
author	ymjr
version	1.0.0
license	MIT
usage	后台常驻。为携带 `customData.template` 的文本元素提供底层的“运行时变量替换”能力，使得文字元素可以成为动态展示外部数据的容器。
features	拦截 `beforeWrapText` 钩子 根据元素 ID 到全局上下文 `window.templateMap` 中匹配对应渲染内容
dependencies	需要与其他生成模板数据的脚本配合使用
autorun	true
