/**
* Batch Audit Example - Audit Proof Circuit
*
* This example demonstrates how to generate multiple audit proofs
* in batch for compliance reporting or bulk operations.
*
* ⚠️ Note: This example uses sandbox mode. For production, use API key authentication.
*
* Prerequisites:
* - npm install @affixio/sdk
* - npm install typescript @types/node ts-node
*
* Run with: npx ts-node examples/batch-audit.ts
