+- **内联链接不变**：夹在句子里的链接保持普通样式（`这是一句带 [链接](https://example.com) 的话` → 不会变卡），所以不会把整篇变成卡片墙
+- **抓取失败一律回落普通链接**：404、无 OG、超时（4s）、站点拒爬都不影响构建
+- **每篇最多 10 张卡**，超出的回落普通链接（防止文章变卡片流）
+- **缓存**：结果存 `content/.link-cache.json`（入仓，保证构建确定性）；条目 30 天后自动重抓。想强制刷新某条——删掉该 URL 的条目即可
+- 缩略图取 `og:image`，无图不占位；图标取站点而非第三方 favicon 服务

+
+后台地址 `/admin/`（gitea 账号登录）。三类媒体都有后台入口，不必手写路径：
+
+### 图片
+
+文章编辑器里插入图片 → 自动上传到 `content/posts/assets/` 并写入 `./assets/...`
+相对路径（走 Astro 图片管线，自动优化）。**不要手改成 `/assets/...` 绝对路径**。
+
+### 视频（frontmatter 字段，正文后自动渲染）
+
+1. 文章编辑页「附视频」字段上传（自动落 `public/media/`，路径写 `/media/<name>.mp4`）
+2. 正文读完后自动出现 `<video controls preload="metadata" playsinline>`，全宽圆角黑底
+3. 「视频封面」填 `/media/xxx.jpg` 可自定首帧；留空浏览器自取
+4. 无视频字段 → 该区块不渲染（零占位）
+
+体积纪律：mp4/webm ≤50MB 走 `public/media/`（构建原样拷贝，不转码）；
+更大的请按上文「体积纪律」放仓外 store（该场景 build.sh 同步段待首次出现时补）。
+
+### 链接
+
+markdown 原生语法，无需任何配置：
+
+```markdown
+[文字](https://example.com)
+```
+
+想让链接显示成 OG 预览卡（带标题/描述/图标），把它**单独放一行**即可——规则见上文「链接卡片（OG 预览卡）」。
+
+### 页面文案（主页/关于/开源）
+
+后台「页面文案」下三个入口：
+
+| 入口 | 文件 | 可改内容 |
+|---|---|---|
+| 主页设置 | `content/site/home.yaml` | 身份语 tagline（zh/en） |
+| 关于页 | `content/site/about.yaml` | 身份陈述段 intro（zh/en） |
+| 开源页 | `content/site/opensource.yaml` | 叙述 blurb/blurb_after、仓链接、置顶项目 pinned |
+
+- 中文/英文各一个字段，页面按语言取；**留空则该字段回落默认文案**（构建不会炸）
