选择如何将 DocumentContent 渲染为字符串。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Plain

纯文本：段落以换行连接，表格以逗号分隔。

Annotated

结构化标注（例如 [段落 3]、[表格 1: 2行x3列]）。

Outline

仅标题，Markdown 风格。

Fields

max_level: u8

要包含的最大标题级别（1–6）。超过此级别的标题将被省略。

Stats

聚合统计：段落/表格/图片/字数计数。
