 ### Added
 
 - **`den.Marshal`, `den.LinkFields`, and selective `WithFetchLinks(fields...)`.** `den.Marshal` is an output JSON marshaller that emits hydrated `Link[T]` values as their nested object anywhere in the value graph (unloaded links and `json.Marshal` stay the bare id — the storage format is unchanged). `den.LinkFields[T]` enumerates a type's relation fields (JSON name, target collection, slice, eager). `WithFetchLinks` now takes optional field names to hydrate only the chosen links. Together they make relation-expansion (`?expand=`) a thin layer for consumers.
