 * (msg.sender = 0x0) to protect access-controlled shielded state. Gas estimation
 * for owner-gated calls therefore reverts with "Ownable: caller is not the
 * owner". Seismic's `eth_estimateGas` instead accepts a *signed* raw transaction
 * and recovers `msg.sender` from the signature (a "signed read").
 *
 * Signed reads require Seismic encryption metadata and a replay-protected
 * signature. The official client handles encryption and EIP-712 encoding;
 * signing delegates to the wrapped signer without exporting its private key.
 *
 * Only `estimateGas` is overridden. Writes are plain transparent transactions
 * that already work on Seismic, so everything else delegates to the wrapped
 * signer.
