// Fire-and-forget request that wakes the Azure App Service worker.
// The backend sleeps after ~20 min idle (no "Always On" on Free/Shared tiers),
// so the first real call after idle pays a 10-30s cold start. Pinging here at
// page load lets the worker warm up in parallel with the Auth0 redirect, before
// any authenticated data call fires.
//
// `no-cors` is intentional: we don't read the response (an opaque 401/404 is
// fine — the request still reaches the worker and wakes it) and it avoids CORS
// errors in the console for a request the server isn't set up to answer.
