// TransloaditKit 3.5.0. Supply your app’s authenticated signing integration.
// Its backend must authorize params, expiry, processing and destination policy,
// then sign the exact original UTF-8 bytes. Do not reserialize them.
// The signing completion is nonescaping: call it synchronously exactly once
// before the signature generator returns, including denial and timeout.
// Use synchronous transport with a finite timeout, off the main thread.
// The SDK fixes a 24-hour expiry; use backend creation if policy requires less.
// Retain the returned client for the operation’s lifetime.
// Signing guide: https://transloadit.com/docs/sdks/transloaditkit/#user-content-transloaditkit-usage
