+# DoTouch.AI 性能基线 v1.3.0（P1 SEO 落地后）
+
+> 日期：2026-08-09 ｜ 环境：生产构建（`pnpm build`）本地 `next start`
+> 方法：SSG 静态页面实测（HTTP 计时）；完整 Lighthouse/CrUX 需生产域名部署后补充
+
+## 核心数据
+
+| 指标 | 实测值 | 目标 | 状态 |
+|---|---|---|---|
+| TTFB（/vi 首页） | **12-15ms**（3 次实测 12.3/13.3/14.7ms，取中位 13ms） | < 100ms | ✅ |
+| 渲染模式 | 全站 **SSG 静态**（47/47 静态页） | ○ 静态 | ✅ |
+| 首页 JS 首载 | 118 kB（含框架） | — | 待优化 |
+| 控制台页 JS | 114 kB | — | 待优化 |
+
+## 路由包体（build 输出）
+
+| 路由 | First Load JS |
+|---|---|
+| /[locale] 首页 | 118 kB |
+| /[locale]/models | 119 kB |
+| /[locale]/models/[id] | ~119 kB |
+| /[locale]/pricing/catalog | 121 kB |
+| /[locale]/console | 114 kB |
+| /admin | 105 kB |
+
+## 说明与后续
+
+1. **TTFB 极优**（SSG 静态 + 无外部阻塞）——LCP 主要取决于客户端 JS 解析与图片加载
+2. **Lighthouse 完整审计**：需生产域名（`https://dotouch.ai`）部署后，用 Playwright+Chromium 实测 mobile/desktop 各 3-5 轮取中位数（方法见 frontend skill perfection 规则集）
+3. **CrUX 现场数据**：上线后通过 Search Console / PageSpeed Insights 获取（25 周趋势）
+4. 已知优化项（后续 P4）：OG 图 4MB 偏大（可压至 <200KB 提升 LCP 的 image decode）；控制台 JS 按需分割
+
+## 变更影响
+
+- SSG 静态化使所有页面即时返回（TTFB 13ms 级），显著利于抓取预算与用户体验
