  Syndicate has no separate sandbox host or test/live key prefix. Test vs
  production is selected by the EVM chainId in the request: use a testnet chainId
  to operate against test networks with faucet-funded gas. There are no "magic"
  test values to fabricate — the safe testing surface is the public EVM testnets
  below.
