 * <h2>Ed448 Key-Pair Builder</h2>
 *
 * Concrete key generation builder for the Ed448 Edwards-curve Digital Signature
 * Algorithm, standardized in
 * <a href="https://www.rfc-editor.org/rfc/rfc8032">RFC 8032</a>.
 *
 * <p>
 * This builder integrates with the JCA {@link java.security.KeyPairGenerator}
 * under the canonical algorithm name {@code "Ed448"}. It is responsible for
 * producing fresh {@link java.security.KeyPair} instances; key import is
 * delegated to {@link Ed448PublicKeyBuilder} and
 * {@link Ed448PrivateKeyBuilder}.
 * </p>
 *
 * <h2>Usage</h2> <pre>{@code
 * // Generate a new Ed448 key pair
 * Ed448KeyGenBuilder builder = new Ed448KeyGenBuilder();
 * KeyPair kp = builder.generateKeyPair(Ed448KeyGenSpec.defaultSpec());
 * }</pre>
 *
 * <h2>Thread-safety</h2> Instances are stateless and may be reused across
 * threads. Each call creates a new {@link java.security.KeyPairGenerator}.

 * @since 1.0
