## role
Provides widget definitions, schemas, and data source adapters for rendering configurable dashboard widgets from both built-in and external service data.
## files
- __init__.py | Marks the directory as a Python package for the widget subsystem.
- builtin.py | Defines built-in widget kinds that don't require external services, providing their configurations, schemas, and validation. | exp: class:StaticConfig, func:get_builtin_widget_kind(kind: str) → WidgetKind | None, call:BUILTIN_WIDGET_KINDS.get, func:is_builtin_kind(kind: str) → bool, func:builtin_widget_kind_models() → dict[str, type], call:Field, func:validate_builtin_config(kind: str, config: dict[str, Any]) → dict[str, Any], call:builtin_widget_kind_models, call:models.get, call:dict, call:model_cls.model_validate(config or {}).model_dump | dep: typing, media_library_viewer_api.integrations.base, pydantic

## arch
Adapter pattern with modular source integrations that normalize heterogeneous external API responses into a unified widget payload format, complemented by schema-validated built-in widget configurations.
