name: Build Tutorial

# 主仓库 gitea.idealjs.com/idealjs/stack 的 CI：打包新教程站。
# 构建环境全部封装在 apps/tutorial/Dockerfile（node24-alpine + yarn4 + npmmirror），
# runner 用 buildah 无 daemon 执行——不依赖 runner 宿主的 node/docker，也不碰 github.com。
#   源码：gitea API tarball（同机房）
#   产物：滚动 release「ci-dist」资产（node 取自镜像挂载层，原生 fetch 上传）
