Build me a safe educational Python tool that demonstrates how crypto wallet seed phrases work, without trying to break into anyone’s wallet.

I want it to generate BIP39 style 12 word mnemonics, derive Bitcoin and Ethereum addresses from them, and check balances only for addresses I already own or explicitly provide. If a balance is found, save the results to a text file and keep a clear log of what happened during the run. Make it easy to run from the command line, and if it helps, include a Docker option too. Please keep the code simple and readable, and look up current library docs online if you need to.
