BIP39 is used to generate mnemonic seed words and derive a binary seed from them.
BIP32 is used to derive the path m/44'/1237'/0'/0/0 (according to the Nostr entry on SLIP44).
This is the default for a basic, normal, single-key client.
Other types of clients can still get fancy and use other derivation paths for their own other purposes.
