// Proves, against a real production build (next build + next start, plan D18), that a
// visit actually uploads a session replay segment — not just that the SDK is configured
// to try. instrumentation-client.ts's /api/_conusai/* calls are same-origin and answered
// by the platform's edge on a real deployment (docs/how-to/use-platform-analytics-in-an-
// app.md §"Why this works"); this app has no edge in front of it here, so the test stands
// in for it with the minimum the SDK needs: a session id from /ids, and a place to post
// the envelope. This caught the stage regression (2026-10-11, showcase plan D24) where
// mode: 'always' alone produced zero /api/_conusai/envelope requests because replay is a
// 'consented' item and the default consent mode never sends those.
