/**
|
||
* MetaLab Editor — Vditor Markdown 所见即所得编辑器
|
||
*
|
||
* Vditor 原生支持 MD + WYSIWYG,后端存储 Markdown。
|
||
* 图片上传复用现有 /api/posts/upload-image,后端已返回 Vditor 原生响应格式。
|
||
* 安全模型:前端输出 MD(纯文本)→ 后端直接存储 → 详情页客户端 Vditor 渲染为 HTML。
|
||
*
|
||
* Shortcode 扩展语法([zone:type:params]):
|
||
* 输入 [zone: 触发自动补全,选择类型后自动生成对应语法。
|
||
* 支持的 shortcode 详情见 /docs/vditor-migration-plan.md
|
||
*
|
||
* Vditor 全局对象由 /static/vditor/dist/index.min.js 提供。
