# StartOS Registry - VPS Setup Script
# ============================================================================
# Run this on your Hetzner VPS as root (or with sudo).
# It installs Node.js, nginx, certbot, creates a service user,
# deploys the registry, and sets up TLS.
#
# Usage:
#   scp -r startos-registry/ root@YOUR_VPS_IP:/tmp/
#   ssh root@YOUR_VPS_IP
#   bash /tmp/startos-registry/scripts/setup-vps.sh
#
# Prerequisites:
#   - DNS A record for registry.satsflows.com pointing to your VPS IP
#   - Ubuntu 22.04 or Debian 12
# ============================================================================
