ユーザーが自分の写真を1枚アップロードし、応援しているチームを指定します。その人物が試合で熱烈なサポーターとして写る6枚の個別の写真を生成します。試合当日のカルーセルです。

手順

1. 2つの入力を受け取ります。 写真（ローカルパスまたはURL）と応援しているチームです。写真がローカルパスの場合は、アップロードします（upload_asset → presigned_url に PUT → public_url を使用）。生成されたURLを photo と呼びます。

2. チーム情報を補います。 チーム名をもとに、{team} と {kit colors}（メインカラー2色とストライプのパターン。例：Argentina → "sky-blue and white vertical stripes"）を補います。クレストやロゴではなく、色を説明します。

3. 6枚の写真を生成します。 以下の各プロンプトにつき、generate_image_edit を1回ずつ、合計6回個別に呼び出します。毎回同じ photo を images として渡します（これにより顔が同一になります）。各呼び出しの設定：provider: gpt-image-2、images: [photo]、aspect_ratio: 3:4、quality: medium、output_format: png。

4. 6枚の個別画像を順番に提供します。ファイルは6つです。1枚の画像をパネルに分割することはできません。
