// CreateProjectModal.jsx — §22 S5. The create-project form the deployment
// directory's "Create your first project" / "New project" control opens, gated
// on the viewer's `can_create_project` capability (a global Owner action).
//
// The form lets the Owner choose a project id (a slug, not "default"), a display
// name, the type of its initial (default) collection, a visibility, and an
// optional content-repo name (defaulting to `<id>-content`). The backend
// provisions the Gitea content repo, commits the project to projects.yaml,
// re-mirrors the registry, and returns the new project; on success the caller
// refreshes the directory (and the N=1 redirect then lands in the new project).
