 *  - **`number` balance fields** → multiplied by
 *    {@link JOULE_MICROUNITS_PER_UNIT} (rounded) and stored as decimal-
 *    string `bigint` microunits.
 *
 * Already-upgraded DTOs round-trip unchanged. The function never throws —
 * unrecognized field shapes coerce to `'0'` so the caller gets a fully
 * populated DTO it can persist on next write.
 *
 * @see asset-account-store-generalization spec, Requirements 1.4, 2.5, 2.6.
