🔒 Security Notes

• The server connects via SSH using key-based authentication (no passwords).
• Commands run with the privileges of the configured SSH user.
• Service management and firewall tools use sudo — ensure your SSH user has appropriate sudoers permissions.
• The server maintains a persistent SSH connection that is automatically reconnected if dropped.
