# ==================================================
# OCDP Docker Compose (frontend + gateway layer)
# ==================================================
# 使用方式:
#   docker compose -f docker-compose.yml \
#     -f ./backend/docker-compose.yml \
#     --profile backend up --build -d
#
# 说明:
#   - 本文件只负责前端构建和 Nginx。
#   - Backend / PostgreSQL / pgAdmin 由 backend/docker-compose.yml 提供。
#   - Nginx 统一监听 80/443（默认映射 WEB_HTTP_PORT=80、WEB_HTTPS_PORT=443），
#     根据路径转发：/api/* → backend，其他路径 → 前端服务。
