A cli to interact with the Acurast Cloud.

/**
 * A `@polkadot/api` {@link Signer} that delegates signing to a browser wallet
 * via the local bridge server. Each `signPayload`/`signRaw` call registers the
 * payload, opens the bridge page, and waits for the wallet's signature.
 *
 * A single instance serves multiple sequential signatures (a deploy signs
 * `deploy`, then later `setEnvironments`), so polkadot.js assembles and submits
 * the extrinsic over the CLI's own RPC connection — the CLI keeps full control
 * of submission + progress reporting.
