**As an** administrator creating a sub-type
**I want to** be guided through creation step by step, the way the project initiation wizard works
**so that** I can set up a sub-type and its reuse choices without hunting across admin tabs, and accept sensible defaults to create one quickly.

## Acceptance criteria

* Creating a sub-type runs as a multi-step wizard modeled on the project creation wizard, not a single form.

* The wizard guides me through: choose the parent type (and, where applicable, ownership), set the variant label, choose the reuse mode per aspect (workflow, form configuration, PDF and subject) before confirming.

* Each step validates before I advance, and I can go back to change an earlier step without losing later input

* Defaults are pre-filled, with every aspect Linked to the parent, so I can accept defaults and create in a few clicks

* The wizard is launched from the grouped Types index "Add sub-type" action and, for project-owned sub-types, from project settings Begin of the insertion

* The wizard is _not_ used for editing existing types, it will remain as tabs


## Technical considerations

* The new type is saved immediately after the first step, so we do not have to forward each form input between steps

* We need to find some way to render pages in both the tabbed and wizard styleEnd of the insertion


## Permissions and visibility considerations

* **To whom is this feature visible?** Instance administrators (global sub-types); project members with `:manage_subtypes` (project-owned sub-types).

* **When is it not visible?**

* Feature flag turned off

* users without the relevant management rights.

## Out of scope

* Editing an existing sub-type through the wizard; editing stays in the tabbed administration. The wizard is for creation only
