//! On-chain ENSIP-25 verification example.
//!
//! Run with: `cargo run --example verify --features provider`
//!
//! Uses official ENSIP-25 test data (verified in both directions):
//! - ENS Name: `ens-registration-agent.ses.eth`
//! - Agent ID: `26433`
//! - Registry: ERC-8004 `IdentityRegistry` on Ethereum Mainnet
