- 如果表格结构复杂优先使用HTML table标签而不是Markdown表格语法**
8. **重要确保内容完整性
- 不要截断任何内容
- 保持原文的完整性
- 所有重要信息都要包含在思维导图中**
9. 输出格式直接输出Markdown内容不要添加任何说明文字或代码块标记`,J=`请分析以下文档内容并生成结构化Markdown

`).trim(),me=async(j,G)=>{const ne=j||`你是一位Markdown格式转换专家你的任务是将用户提供的文章内容精确转换为结构化的Markdown格式请遵循以下步骤
提取主标题 识别文章最顶层的主标题通常为文章题目或书名并使用Markdown的 # 级别表示
识别层级标题 从文章内容中提取所有层级的内容标题从主标题后的第一个标题开始Level 1 Level 4判断层级依据
视觉与结构特征 如独立成行/位置行首格式加粗编号如 1., 1.1, (1), -
语义逻辑 标题之间的包含和并列关系
在Markdown中使用相应标题级别
Level 1 标题用 ##
Level 2 标题用 ###
Level 3 标题用 ####
Level 4 标题用 #####
精确保留原文标题文字不得修改概括或润色
处理正文内容 对于每个标题下的正文内容区块从该标题后开始直到下一个同级或更高级别标题前
直接保留原文文本但根据内容结构适当格式化为Markdown
如果内容是列表如项目符号或编号列表使用Markdown列表语法例如 - 用于无序列表1. 用于有序列表
保持段落和换行不变
**重要如果原文档中包含图片请按以下方式处理
1. 识别图片在文档中的位置和上下文
2. 根据图片内容生成准确的描述文字
3. 在相应位置插入图片占位符![图片描述](图片路径)
4. 图片描述要准确反映图片内容图片路径可以是相对路径或占位符
5. 确保图片占位符放在逻辑上合适的位置**
