/**
 * Canonical timestamp schema: ISO 8601 UTC string on the wire, `DateTime.Utc`
 * in memory.
 *
 * Decoding accepts any string `DateTime.make` understands and normalizes it to
 * UTC; malformed strings fail decoding. Encoding always produces an ISO 8601
 * UTC string (e.g. 2024-01-15T12:00:00.000Z), so wire formats are unchanged
 * from the previous hand-written ISO-string handling.
 *
 * The encoded string side carries the `format: "date-time"` annotation so
 * OpenAPI and JSON Schema emissions preserve the timestamp format.
 *
 * @experimental This API is unstable and may change without notice.
