 * Reject a payload that cannot survive a JSON round trip, on the way in and on
 * the way out. The seam promises owners their payload comes back exactly as
 * written, and both directions can break that: a document may spell `.inf` or
 * an alias cycle, and an owner may hand over a `Date`, a class instance, or a
 * `bigint` that this document has no faithful spelling for. Neither the value
 * nor any nested value is quoted in a diagnostic.
 * @param where - the subject named in a diagnostic, already free of any value.
 * @param value - the payload or nested value to admit.
 * @param seen - objects on the current path, for cycle detection.
 * @throws TypeError naming `where` when the value cannot round-trip.
