-// Re-export or Wrap
-// Since ContentItem and Order are in the same package 'dto',
-// we don't need type aliases unless we want to rename them.
-// If creator.go uses them, it can use dto.ContentItem directly.
-// But creator.go is in `v1` (package v1) and imports `dto`.
-// So it uses `dto.ContentItem`.
-// So we don't need aliases here if the original types are in this package.
-
-// However, if the originals were in `content/dto` and `user/dto` and we moved them to `v1/dto` (this package),
-// then we just have them defined in `content.go` (dto) and `user.go` (dto).
-// So aliases are not needed if they are in the same package.
