 * ======================================
 * 共通SCSSに不足していたもの
 * ======================================
 *
 * 値の粒度不足：container の内側余白（60px）・section 112px/96px・gap 12/14/28/32/36/72/88px が utility に無い
 * 値の粒度不足：letter-spacing 0.04/0.06/0.08/0.16/0.24/0.3/0.36em、font-size 11/13/15/17/21/26/30/34/52/60px が utility に無い
 * 状態不足：背景が左から右へ伸びるホバー（background-size）、ナビ下線が中央から伸びるホバー
 * 構造不足：ドロップダウンの幅をナビの左端〜右端にそろえる仕組み（header__dropdown は項目ごとの幅）
 * 構造不足：番号を点線でつなぐ横3列の工程（card-flow は矢印・角丸カード）
 * 構造不足：［DXF］［PDF］ラベル付きのダウンロードボタン、型ごとに見出し行が入るダウンロード表
 * 装飾パターン不足：英字＋日本語＋短い線の見出し（heading 系は英字が大きい前提）
 * 装飾パターン不足：角なし・1px枠のボタン（btn は角丸10px・2px枠）
 *
