/* ===========================================================
   AI real CG 公式サイト — レイアウト案B（index-b.html 専用）
   参考: studio.design/ja/business/ の構成手法
   ・全幅の濃色帯 ↔ 白/グレー帯を交互に置いてリズムを作る
   ・見出しは中央寄せ＋ドット付きのピル型ラベル
   ・MVは濃色地。右のビジュアルを画面右端まで流す
   ・特徴で選ぶは「大2枚＋小4枚」の非対称グリッド
   ・ギャラリーは濃色地の全幅
   ・最終CTAは黄色の全幅帯（黄×黒を反転して使う）
   色・フォント・ボタンは common.css のトークンをそのまま継承（Make House 踏襲）。
