"""
Export the compiled Greeter contract's ABI to a plain JSON file, so the
separate web3.py script (interact.py, one level up) can load it. Ape already
knows the ABI internally; this just writes it out in a format a different
library can read.

Run it with (after `ape compile` has run at least once):
    ape run get_abi --network ethereum:sepolia:<your-rpc-url>
