/**
|
||
* 视觉类节点统一大预览：
|
||
* - **在 ReactFlow 节点 DOM 内**作为 absolute 元素，底边贴当前缩略图上方边缘
|
||
* - 跟随 ReactFlow 画布 pan/zoom 一起变化（属于"无限画布"的一部分）
|
||
* - 媒体按"自然像素分辨率"渲染，不做 max 尺寸限制
|
||
* - 不 pinned 时：pointer-events-none，依赖调用方传入 visible
|
||
* - pinned=true：强制 visible，pointer-events 开启，可点 × 关闭
|
||
* - 用法：渲染在节点根层，不要放进 overflow-x-auto 缩略图滚动条里
