## role
Provides a plugin-style integration framework for declaring and registering external service connections (e.g., Grafana, Jellyfin, Prometheus) with config schemas, secrets, and widget definitions for the media library viewer API.
## files

## arch
Registry pattern with abstract base classes and dataclass-driven configuration models; each integration is a self-contained module registered in a closed registry that supports lookup, enumeration, and declarative widget/kind definitions.
