Are there any good technical explainers on how Farcaster uses Largeblob? cc @v @nicholas

WebAuthN issues a keypair, and in the registration request we require largeBlob support. We basically ignore the regular keypair and just take the credential id to subsequently request the largeBlob to store the mnemonic. LargeBlob extension support requires creating an auxiliary key on the enclave to encrypt data

Would be down to formalize this more, but basically largeBlob is a passkey extension that Warpcast uses to securely store and retrieve your seed phrase
