 * ======================================
 * 共通SCSSに不足していたもの
 * ======================================
 *
 * 【値の粒度不足】
 *  - clamp() による可変値（余白 80〜130px・見出し 46〜92px 等）を表す utility がない
 *  - .mb-40 以上は tablet で自動半減するため、半減しない 44/48/56/64px の余白が表現できない
 *  - コンテナ幅 1400px（左右 clamp 余白）/ 880・960・1120px の幅がない
 *  - body font-size が tablet 14px / SP 12px に縮小される（本デザインは全幅 16px 固定）
 *  - ヘッダー切替 BP が 1100px 以下（本デザインは 1099px 以下）
 * 【指定方向不足】
 *  - 写真に重ねる大きな番号（右下／左下で写真外へはみ出す）の配置指定
 * 【状態不足】
 *  - hover 時に子要素（丸矢印）だけ translateX するリンク
 *  - lightbox の BEFORE 画像にぼかしフィルタを引き継ぐ状態
 * 【構造不足】
 *  - 日本語（上・小）＋英字（下・大）の縦積み見出し（heading は英→日の順・サイズ固定）
 *  - flex-basis + flex-grow 比率による 2カラム（column2 は%固定で折返し幅を制御できない）
 *  - auto-fit / minmax の自動列 grid（grid-auto は 250px 固定）
 *  - dt/dd 横並びの折返し式会社概要表、STEP番号を線でつなぐフロー
 *  - 右→左に流れる施工事例マーキー（gallery-scroll は CSS アニメで、ホバー停止・CMS 複製に非対応）
 *  - ラジオボタンのボタン型選択肢
 * 【装飾パターン不足】
 *  - 斜めの光（グラデーション三角 clip-path）、山並み区切り、角を落とした写真（clip-path）
 *  - 見出し英字の3色グラデ文字（#51adde→#1866b2→#1f3a86）
 *  - 和紙調ノイズテクスチャ背景
 *
