//! Tooling Access control plane.
//!
//! Tooling Access provisions a single multichain, read-only endpoint per
//! account and mints short-lived ES256 session JWTs. Those JWTs are consumed by
//! the [`crate::rpc::RpcApiClient`] to authenticate RPC calls directly against
//! the provisioned endpoint; the private signing key never leaves the server.
//!
//! These routes live on the same Admin API base URL as the rest of this client.
//! Note this is distinct from [`super::AdminApiClient::create_jwt`], which
//! registers a public key on an endpoint's security config — here we mint the
//! session tokens themselves.
