- Remove local-host-production.yml for single-server setups
- Remove remote server sections from sablier.yml for local deployments
- Remove remote server entries from homepage services files when no REMOTE_SERVER_HOSTNAME is set
- Prevent placeholder replacement failures on files not needed for local deployments
