/**
 * A Base64-encoded binary value stored as an Elasticsearch/OpenSearch
 * `binary` field.
 *
 * - **ES/OpenSearch mapping:** `{ type: 'binary', doc_values: false }`.
 *   `doc_values` is always forced off because binary fields are not
 *   searchable and can be very large. Honors `indexed: false` (emitted as
 *   `index: false`).
 * - **GraphQL:** `String`.
 * - **xLucene:** `String`.
 *
 * Because it is neither indexed for search nor stored as doc values, a
 * `Binary` field is opaque storage — you can retrieve it by `_source` but
 * cannot filter, sort, or aggregate on it. This can be useful to store
 * small files (thumbnails, audio, scripts, cryptographic keys, bit vectors)
 * that can be filtered, sorted, and aggregated by metadata fields stored
 * on the same record.
 *
 * @example
 * const config: DataTypeConfig = {
 *     version: 1,
 *     fields: { thumbnail: { type: 'Binary' } }
 * };
