 后台编辑器里：**选中文字 → Insert 菜单 → 「排版（字体/颜色）」→ 面板里点一个类**，文字即被 `<span class="…">` 包住；点已套用的片段可改类，Backspace 可整体删除。
 面板里的两类与上表一一对应（字体 8 / 颜色 9），类清单单一事实源在 `public/admin/typography-classes.js`。
 
+## 三层排版架构（全站，不只文章正文）
+
+**层 1 · 页面文案富文本**：后台「页面文案」里的 tagline / subtitle / blurb / blurb_after / intro / 关于页 blocks 的 prose 块，全部走同一条富文本管线（markdown + raw + 内容净化 + class 白名单 + 链接卡片）。可以直接写：
+
+```yaml
+tagline:
+  zh: '<span class="font-kai c-blue">写作者</span> · 读者 · 快门按压者，拥抱开源。'
+```
+
+渲染入口唯一：`src/lib/site-content.ts` 的 `renderRich()`（行内场景传 `{ inline: true }` 自动剥外层 `<p>`，否则 `<p>` 套 `<p>` 会被浏览器拆散）。
+**不开放**：导航/页脚/按钮等硬编码界面外壳——那是 UI 不是内容。
+
+**层 2 · 页面级排版覆盖**：每个页面单例（`content/site/*.yaml`）可加：
+
+```yaml
+typography:
+  font: font-kai        # 本页正文默认字体类（可选）
+  accent: c-blue        # 本页强调色类（可选）
+  scale: 1.1            # 字号缩放 0.8–1.25（可选）
+```
+
+实现是在该页内容容器上挂 `.page-typo` + CSS 变量（`--page-font / --page-accent / --page-scale`），**不写全站 tokens**——其它页面零影响（已在图库/书架/文章/装备页验证隔离）。白名单外的类名会被忽略。
+后台入口：「页面文案 → 各自页面 → 页面排版覆盖」。
+
+**层 3 · 艺术字体**：`font-art-kuaile`（站酷快乐体，艺术字专用类）。⚠️ **仅用于标题/短句**：艺术字字形大，CJK 切片体积高（实测用到页 +163KB），长段使用会显著抬高单页字体成本。
