// All Google API calls are routed through the on-prem remote agent so the
// request originates from the whitelisted IP subnet. The API key is
// restricted by IP; calls direct from the cloud bot IP get 403 with
// API_KEY_IP_ADDRESS_BLOCKED. The remote agent runs inside the corporate
// network, so its egress IP matches the key's allow-list.
//
// `insecure: true` is set even though Google's public certs are trusted,
// because the corporate network the agent lives on intercepts outbound
// HTTPS with an SSL-inspecting proxy that presents an internal-CA chain.
// Without the flag Node throws SELF_SIGNED_CERT_IN_CHAIN on any outbound
// TLS. Trust is already delegated to that proxy by being on this network,
// so the scoped per-request bypass is consistent with SIW.
