   OPCON LP - CV改善 v20260505 (firstview-engagement)
   作成日: 2026-05-05
   背景:
     - Microsoft Clarity 直近14日: /lp/webroot/ の **平均スクロール深度 15.97%**
       → ファーストビューしか見ていないユーザーが大半。
       → 価格優位・スクロール誘導をヒーロー上で完結させる必要あり。
     - tldv 3/26 合意 (Shohei氏 × 谷藤): "価格は比較で見せる" / "動画は muted 自動再生"
     - 既存 v3 (価格比較行 + Trust strip) は価格セクション以下に効く施策。
       v4 はそこへ到達する前段（hero）の改善に専念。
   このv4で追加:
     1. ヒーロー直下「ミニ比較バー」(.mv-mini-compare)
     2. スクロール誘導アローの強化 (.mv-scroll-hint--v4)
     3. ヒーロー動画 muted autoplay コンテナ (.hero-inline-video)
