/* ============================================================
   OCR 自動認識 体験デモ (2026-09-21)
   「レシート写真 → スキャン → 構造化データ抽出 → 仕訳生成」の
   フローを可視化する専用ショーケース。ai-accounting.htmlの実際の
   OCR処理(professional_ocr_processor.js)が返すフィールド構造
   (vendor_name/invoice_date/total_amount/tax_amount/items/
   expense_category_suggestion)に忠実な、代表的なサンプルデータで
   構成。純CSS/JSアニメーションのみ、実APIは呼ばない。
