Server.Dockerfile

# ==============================================================================
# Server-Only Dockerfile for OpenFrontIO
# ==============================================================================
# This builds and runs ONLY the game server (no nginx, no Cloudflare tunnel)
# Perfect for local development or self-hosted deployments
#
# Usage:
#   docker build -f Server.Dockerfile -t openfront-server .
#   docker run -p 3000:3000 -p 3001-3020:3001-3020 --env-file .env openfront-server
