/* 越前ひらた工務店 ── 実績ビフォーアフター型（工務店・リフォーム）
   署名的インタラクション＝ドラッグできるビフォー/アフター比較スライダーを主役に据えたLP。

   配色は「住まいの素材」から取っている。落ち着いた実績系。
     チャコール … 焼杉・鉄骨の温かい黒（純黒は使わない）
     温かい白   … 漆喰・無垢材の生成り
     木のブラウン … 造作材・フローリングの茶。主アクセント
     アースグリーン … 土壁・下地・庭木の緑。副アクセント
   参照実装 clean の「白×鮮やかな青」とは意図的に別方向にしている。

   ★クラス名の注意★
   背景装飾用クラスとコンポーネント用クラスに同じ名前を使わないこと。
   ダークモード非対応（商用LPは見え方を固定したほうが扱いやすい）。
   角丸は小さく・キビキビと。差し替え箇所は index.html 側のコメントを参照。 */
