/* ============================================================
   OCR live scan — 実際のアップロード処理中に表示する視覚効果
   ai-accounting.html の handleInvoiceUpload() 用 (2026-09-21 追加)。

   ホームページの components/landing/styles/ocr-demo-widget.css と
   同じデザイン言語(ダークガラス+スキャンライン+バラ色アクセント)だが、
   ここでは「ユーザーが実際にアップロードしたファイル」をスキャン対象
   として表示し、進捗は不確定(indeterminate)アニメーションのみを使う。
   実際のOCR処理はバックエンドから一括レスポンスのみで、途中の
   段階的な進捗は取得できないため、偽の完了率・偽の完了順序は
   一切表示しない(3つのステップは同時に「処理中」を示すだけ)。
