# Plaza 独立部署 → 105（与 Memind H5 解耦，仅共享同机 API）
#
# 架构：
#   plaza.tkmind.cn
#     /plaza、/_next  → goose-plaza-web :3002  (/root/plaza/web)
#     /api、/auth、/u → goose-h5 :8080         (/root/tkmind_go/ui/h5)
#
# 用法：
#   pnpm deploy:plaza-105
#   pnpm deploy:plaza-105 -- --skip-build
#   pnpm deploy:plaza-105 -- --no-restart
#
# 前置：
#   1. DNS: plaza.tkmind.cn A → 120.26.184.105（公网入口）；运维/部署直接使用固定公网 IP
#   2. H5 已部署：pnpm deploy:105（提供 Plaza API + 登录 + 发布页）
#   3. 可选：cp deploy/plaza-105/plaza-105.env.example deploy/plaza-105/plaza-105.env
