// --- telemetry isolation (U7) ---

// MEDIA_USE_TELEMETRY_HOST override read at the point the POST URL is built.
// This test proves that seam actually intercepts a real event end to end: a

// posts to a local HTTP server instead of production, and the server actually
// receives it (not just "nothing happened because nothing was listening").
