// src/utils/downloadBlob.ts
// (Billing-Aware Export), Task 10 - tiny Blob -> anchor download helper, extracted from
// downloadBundleJson.ts's inline Blob -> createObjectURL -> anchor-click -> revoke pattern (the only
// other place in the codebase that triggers a client-side file download). BillingExportPage uses this
// directly rather than repeating the pattern a third time; downloadBundleJson.ts itself is left as-is
// (already deployed/verified for the B3 legal-export flow - not worth touching for this).
