OrderBookTrade/v2-migration ? reverse-engineered prompt

Build me a clean, easy to read migration guide site for Polymarket CLOB v1 to v2, aimed at API traders, makers, and bot developers who need to move without breaking live trading.

I want it to explain the real risks in plain language, like the new exchange contracts, pUSD collateral, signature changes, wallet and allowance checks, order lifecycle differences, WebSocket and REST reconciliation, and how to avoid ghost fills. Include a simple step by step safe migration flow, a checklist for going live, and a few code examples for initializing the v2 client and placing a small test order.

Make it feel practical, not like generic docs. Highlight what usually goes wrong during the cutover, what to verify before increasing size, and what to do during downtime and cancellation windows. If you need current details from the official docs, look them up online and keep the guide accurate.
