(t *testing.T, handler http.HandlerFunc, token, text string)

// active profile and the live llm.Client so cloud auth headers travel as in
// production.

	if token != "" {
		m.cfg.ActiveProfile().Key = token
		m.cli.Token = token

	mm, cmd := m.submit(text, text, promptEntry{display: text})
	out, _ := drain(mm, cmd)
	return out.(Model)
