Create kid site (RomeoBaby)
SSH into the target VPS and deploy MasterAdminSystem from Git (MASTERADMIN_GIT_CLONE_URL on this server). One site per VPS; installs to /var/www/romeobaby-site.
Use HTTPS on this admin site in production. SSH password, optional MongoDB URI, and optional Cloudinary keys are sent to this server once per request. SSH password may be saved in Mongo for sync actions; Cloudinary API key and secret are written to the kid VPS only (cloud name is saved on RomeoMother for the sites list). Do not use untrusted HTTP for production secrets.
