"""Pretty-print + ensure_ascii=False on `aborist query` output.

The CLI default emits a human-readable render of the query result;
``--json`` switches to the raw record. Both paths must:
  - render unicode literals (no \\uXXXX escape sequences)
  - present the answer prominently; metadata is supporting info
