OffsetPage
Simple list envelope used by aggregate endpoints that are not cursor paginated (e.g. user groups, user onboarding, event types). No cursor or offset metadata is returned — the full result set is in `data`. `data` is intentionally not typed here: each response composes this envelope with `allOf` and supplies its own `data.items` ($ref to the resource), so the item type is always the endpoint's resource.
A object value.
