- astro i18n(zh 默认无前缀,en /en/)+ locale.ts 路径工具
- Header 语言切换(同路径跨前缀跳转,预构建毫秒级)
- /en/index + /en/archives/{slug}(postsEn 优先,缺译回退 zh 正文
+ AiTranslatedBadge 虚线标注 TMT);en RSS(标题回退同策略)
- BaseLayout hreflang 双向 + x-default 指向 zh 源
- posts-en 集合(postsSchema.extend locked 润色锁)
- 坑:ts 端点文件误带 --- 开头会以 undefined:2:7 报 Unexpected token
验证: astro build 18 页 exit 0;/en/ 六文章路由+首页+rss 产物断言过;
zh 侧零回归(11 页不变);hreflang 抽查 dist/index.html
