// (FLIGHT_TEST_HOOKS=1; no real credentials in test code), then apply it BOTH ways the client uses —
// localStorage for the app's own fetches (lib/authClient.ts reads it) and context extraHTTPHeaders
// so page.request.* calls in specs carry X-Flight-Session too.

// supported the override since v1.1.0; this helper just never forwarded it). No arg = the suite's
// usual local player, exactly as before.
