# 办公室单机部署（docs/04-部署架构.md §三 精简方案 + §五 第一阶段用 Compose）：
#   app-api(8081) + admin-api(8080，只绑本机) + transcode-worker + PostgreSQL 18 + Redis
#   转码 worker 与在线服务**同机但独立进程/容器**（§8.5 隔离要求：不抢在线服务资源）。
#
# 用法（目标主机需要 Docker + Compose）：
#   cp .env.example .env    # 填密钥与数据库密码
#   docker compose up -d --build
#   tools/smoke.sh
#
# 本文件在本机**未验证**（本机没有 Docker），见 DEPLOY.md「未在本机验证的部分」。
