+# 222_79 简化 paragraph/subparagraph 标题样式机制
+
+## 如何测试
+
+1. 编译：`xmake b stem`
+2. 启动 Mogan，新建空白文档。
+3. 依次插入 **Paragraph** 和 **Subparagraph**（通过 `Structure → Section` 菜单或快捷键）。
+4. 确认 paragraph/subparagraph 标题显示为**粗体短标题样式**（`sectional-short-bold`），上下保留原有间距（`0.5fn` / `0.25fn`）。
+5. 将光标置于 paragraph 或 subparagraph 标题内，打开右侧 **Focus** 菜单，确认**无 "Title style" 选项**（此前存在）。
+6. 分别切换文档类型为 **Article**、**Book**、**Generic**，重复步骤 3-5，确认表现一致。
+7. 确认 section、subsection、subsubsection 的 title-style 切换功能**不受影响**。
+
+## 2026/04/30 实现说明
+
+### What
+
+移除 paragraph 和 subparagraph 独立的 `title-style` 样式切换机制，将其标题渲染统一为 `sectional-short-bold`，不再支持与其他章节标题一样的 "left/centered" 样式偏好设置。
+
+#### 修改文件
+
+**TeXmacs/packages/section/section-base.ts**
+- 移除 `paragraph-title-style` 和 `subparagraph-title-style` 的默认值赋值（原为 `left`）。
+- 移除对应的 `drd-props` 声明。
+- 移除 `paragraph-title-render` 和 `subparagraph-title-render` 宏定义（原通过 `sectional-select-bold` 根据 `title-style` 选择渲染方式）。
+
+**TeXmacs/packages/section/section-article.ts**
+- `paragraph-title` 宏：由 `<paragraph-title-render|...>` 改为 `<sectional-short-bold|...>`。
+- `subparagraph-title` 宏：由 `<subparagraph-title-render|...>` 改为 `<sectional-short-bold|...>`。
+
+**TeXmacs/packages/section/section-book.ts**
+- 同上，paragraph/subparagraph 标题渲染改为 `sectional-short-bold`。
+
+**TeXmacs/packages/section/section-generic.ts**
+- 同上，paragraph/subparagraph 标题渲染改为 `sectional-short-bold`。
+
+**TeXmacs/progs/text/text-menu.scm**
+- 在 `focus-get-preferences` 函数中移除 paragraph 和 subparagraph 对应的 `"paragraph-title-style"` 和 `"subparagraph-title-style"` 偏好设置入口。
+
+### Why
+
+1. **职责精简**：paragraph 和 subparagraph 是最底层的小节标题，在实际使用中几乎不需要与其他章节（section/subsection）同等级别的 "left/center" 样式切换能力。
+2. **代码简化**：移除两套专用的 `*-title-style` 环境变量、drd-props 和 render 宏定义，降低 section-base.ts 的维护复杂度。
+3. **行为统一**：统一使用 `sectional-short-bold` 渲染，与短标题风格的视觉层级保持一致，避免底层小节标题因样式切换导致版面不协调。
+4. **菜单降噪**：Focus 菜单中不再显示对 paragraph/subparagraph 无实际意义的 "Title style" 偏好选项。
+
+### How
+
+- 在 `section-base.ts` 中清理 `paragraph-title-style`、`subparagraph-title-style` 及其相关宏定义，将其从样式注册体系中彻底移除。
+- 在 `section-article.ts`、`section-book.ts`、`section-generic.ts` 三个文档类型包中，将 paragraph/subparagraph 标题宏直接绑定到 `sectional-short-bold`，保留原有的 `vspace` 间距控制不变。
+- 在 `text-menu.scm` 的 `focus-get-preferences` 分发逻辑中移除对应的两个分支，确保 Focus 菜单不再暴露已废弃的偏好项。
