"cell_editor" import {SPINE_CELL_EDITOR_ROLE} from '@fuzdev/fuz_app/testing/cross_backend/spine_surface_constants.js'; App role the role-shaped-cell_grant cross suite exercises. Registered
with no grant path (grant_paths: []) so it stays a valid registry member
without entering the admin / self-service grant flows — holders are seeded
directly via extra_accounts. Must match the cell_editor entry in the
Rust testing_spine_stub's known_roles (cross-language test contract).
