// Verify account proof steps (outline):
// 1) RLP-decode accountProof nodes
// 2) Reconstruct Merkle Patricia path to account leaf
// 3) Hash and compare with trusted stateRoot
// 4) Verify each storageProof against storageHash

// Obtain trusted stateRoot from a block header; verify proofs locally

// Prove L1 account state for L2 verification: use eth_getProof on L1

// Trustless balance verification: check proof against trusted stateRoot
