  },
  body: JSON.stringify({
  "prompt": "A cozy cabin in the snow at sunset, cinematic lighting."
}),
});

if (resp.headers.get("content-type")?.includes("image")) {
  const buf = await resp.arrayBuffer();
  // use buf to save/display image
} else {
  const data = await resp.json();
  if (!resp.ok) {
    throw new Error(data.error || `Request failed (${resp.status})`);
  }
  const b64 = data.image || data.result?.image;
  if (typeof b64 === "string") {
    const bin = atob(b64);
    const bytes = new Uint8Array(bin.length);
    for (let i = 0; i < bin.length; i++) bytes[i] = bin.charCodeAt(i);
    const url = URL.createObjectURL(new Blob([bytes], { type: "image/png" }));
    // display or download via `url`
