Module eip712 

EIP-712 order signing for the Polymarket CTF Exchange.

Orders on Polymarket are signed typed structured data (EIP-712) against the CTF Exchange contract on Polygon. Two exchange contracts exist:

• CTF_EXCHANGE: Standard binary markets.
• NEG_RISK_CTF_EXCHANGE: Negative-risk (multi-outcome) markets.

Both share the same EIP-712 domain name and version; only the verifyingContract differs.

This module also owns the CLOB V2 contract identities and ordered on-chain approval plan (approval_plan) used by the set-allowances binary.
