+ * 把粘在正文行里的围栏拆到独立行。

+ * 模型经常把 ``` 直接粘在上一行末尾（`…实现细节（game.js）：```js`、`… }````），而
+ * CommonMark 只认整行的围栏（最多 3 个空格缩进）：粘着的 ``` 退化成正文，于是正文被当成
+ * 代码渲染，或者代码块一直不闭合、把后面所有内容一起吞进代码块。
+ *
+ * 判据收得很窄：围栏前面必须是非空白字符，且围栏到行尾只允许剩语言标识（可空）。
+ * 这样整行围栏、缩进围栏、行内代码（单个反引号）都不受影响，代码里出现的 ``` 只要后面还有
+ * 别的字符（`const s = "```";`）也不会被拆开。
+ *
+ * 引用块与列表项开头的围栏（`> ```js`、`- ```js`）是**合法结构**，不是粘住的：整行跳过，
+ * 拆开只会把它们从引用块 / 列表项里挪出来。
