- git 仓只进压缩版（构建用）；原图落 ~/docker_apps/blog/photos-originals/
（迁移器/ingest 双入口写入，幂等），build.sh 独立 rsync 到
staging/photos-originals/（同一静态根，零 nginx 改动）
- lightbox 增「原图」（新标签全尺寸）+「下载」（download 属性带文件名）
- 原图持久保障：store + Phase 0 备份 tar 双留档；存量 21 张已回填（196M）
验证: astro build 11 页 exit 0；dist/gallery 含 lb-original×2 与
photos-originals 引用；staging/photos-originals 21 张实测
Spec: none (用户功能补req：原图查看/下载，跨 Phase 独立小特性)
