   業務整理・AI活用診断Bot 専用CSS
   ------------------------------------------------------------
   すべてのルールを #diagnosisBotRoot 配下にスコープし、
   本番LP側の lp.css / style.css と競合しないようにしています。
   @keyframes 名も diagBot プレフィックスを付けて衝突を避けています。

   本番LPのHTML側では、診断Bot一式を以下のように
   ルート要素で囲ってから、このCSSを読み込んでください。

     <div id="diagnosisBotRoot" class="diagnosis-bot-root">
       ... (診断BotのHTMLブロック) ...
     </div>

   アバター画像は、CSSファイルの配置場所に依存するurl()の相対パス問題を
   避けるため、CSS背景画像ではなく<img>タグのsrc属性で表示します
   （diagnosis-bot.js が window.DIAGNOSIS_BOT_CONFIG.BOT_AVATAR_URL を
   HTMLドキュメント基準の相対パスとしてimg.srcに設定します）。
   このCSSでは <img class="bot-launcher-avatar/header-avatar/bot-avatar">
   の見た目（サイズ・円形・枠線など）のみを定義しています。
