### `custom_fields`
Organisation-defined custom fields are returned keyed by their display
**label** (for example `"SAP ID"`), not by the internal column id.
Fields with no active column definition are omitted; the property is
`null` when the user carries none. Define user custom columns in the
Mercura admin UI.
