embycovers/deploy.ps1

<#
Deploy embycovers to an Asustor NAS over SSH/SCP from Windows PowerShell.

Syncs project files to the NAS, then runs `docker compose build` and
`docker compose up -d` on the remote. All runtime configuration (Emby URL,
API key, ports, volumes) comes from docker-compose.yml — edit it there.

Prerequisites on your Windows machine:
- OpenSSH Client installed. Test with: ssh -V
- SSH enabled on the Asustor NAS.
- Docker / Docker Compose available on the Asustor NAS.

Example:
.\deploy.ps1 -NasHost MATT-NAS -NasUser ssh
