/**
 * Did this request fail because it never reached the server?
 *
 * The widget used to answer "the server is offline" to every failure, and on 2026-09-25 a retired
 * Bedrock model made every new chat fail with a 500 — so every visitor was told the server was
 * offline while it was up and serving. The message sent the investigation at DNS, CORS and CDNs for
 * 110 minutes and told customers something untrue.
 *
 * A status code is the discriminator: it only exists because the server answered. Present means
 * reachable-but-failing, which is a different message to a visitor and a different thing for us to
 * go and look at.
 *
 * An unrecognised failure counts as transport. It is the safer claim — "cannot reach the server"
 * when the truth is unknown is wrong in a way the visitor can act on, where leaving the widget
 * looking hung is not.
