"""Read-only preflight for live trading — verifies credentials, balance, and
market access WITHOUT placing any order.

    python3 preflight_live.py            # uses config.live.json

Checks, in order:
  1. config.live.json parses; private key + funder present
  2. CLOB auth: derive L2 API creds from the key (proves the key signs)
  3. USDC balance + allowance on the funder (proves deposits landed and the
     proxy can spend — the balance the bot will actually trade with)
  4. live order book fetch for one of the followed wallets' recent markets
     (proves market-data access end to end)
  5. Polygon RPC + EOA POL gas balance (needed by auto-redeem)

Exit code 0 = every check passed; anything else prints what to fix.
