   2026-09-02 / FOUR ENTRANCE CARDS / IMAGE POSITION & HOVER CONTROLS
   --------------------------------------------------------------------------
   4つの入口カードの背景画像を、カードごとに調整しやすくするための設定です。

   【背景位置の指定方法】
   --quick-path-position:              PC / タブレット通常時の背景位置
   --quick-path-hover-position:        PC / タブレットのホバー時の背景位置
   --quick-path-mobile-position:       スマホ通常時の背景位置
   --quick-path-mobile-hover-position: スマホでホバー時の背景位置

   値は「横位置 縦位置」の順です。
   例：50% 50% = 画像の中央
       40% 50% = 少し左側を見せる
       60% 50% = 少し右側を見せる
       50% 35% = 少し上側を見せる
       50% 65% = 少し下側を見せる

   【重要：スマホでホバーした時の位置】
   スマホ通常時とホバー時で同じ場所を見せたい場合は、
   --quick-path-mobile-position と --quick-path-mobile-hover-position を
   同じ数値にしてください。

   【ホバー時の画像の見え方】
   --quick-path-hover-dark / --quick-path-hover-dark-2 の最後の数値が
   オーバーレイの不透明度です。
   数値を小さくするほど画像がはっきり見えます。
   例：.25 = かなりはっきり / .40 = 標準 / .60 = 暗め
