+- `GET /v1/user/` and `GET /v1/auth/me` gain a `role` ("owner" or "admin"); the list gains `email` on accepted users.
+- `POST /v1/user/invite` becomes owner only, and always creates an admin.
+- `GET /v1/settings`: `{ "version": "..." }`.
 - `PATCH /v1/user/me`: saves the display name. `GET /v1/auth/me` returns it.
