Media Library is a mountable Rails engine that lists images stored in Active Storage (S3, Google Cloud Storage, Disk — whatever the host app configures) and gives content editors a modal image picker. Drop `media_picker_field` next to any URL field (such as an og:image field) so editors can select an existing image or upload a new one instead of typing a path. Storage-agnostic, namespaced, and publishable.
