// > 2026-04-25: 重新读第 3 节。这个隐喻把价值表达为一组明文条款……

// - 资源行:可选 `- ` 列表前缀 + <类型>:<title> + 日期 + 可选 【status】
|

// 类型用自然词,不预设枚举。Obsidian 渲染成 bullet 列表
|

// - 笔记行:可选 `> ` 引用前缀 + <YYYY-MM-DD>:<body>
|

// 多行 body:blank line 之前都算同一条笔记。Obsidian 渲染成 blockquote
|

// - 不带前缀(裸 `论文:...` / 裸 `2026-04-25: ...`)也兼容;前缀只为 Obsidian 视觉区分
|

// - 渲染顺序 = 写入顺序(Trail 视图就是"按你记录的顺序")
