SDK_TRANSPORT_NETWORK
Cause
The SDK's transport threw before receiving an HTTP response — for example a network failure, a cancelled request that was not a timeout, or a local fetch misconfiguration such as an unbound Window.fetch.
Fix
Inspect logger.error's cause (name, message, stack): the request never left the client. Fix the local fetch/network setup. Do not treat this as a platform outage; SERVICE_UNAVAILABLE is reserved for an actual HTTP 503 from the edge.
