A unit ("Einheit") record. The API returns a very wide row (~90 fields) whose columns vary by category (a solar unit carries module fields a gas consumer does not), so only broadly useful fields are typed — each says where it occurs when not in every category; the index signature carries the rest. Natural-person and confidential data are withheld upstream, so operator names may be anonymised (e.g.
"natürliche Person (ABR…)").
