 *    （上下 clamp(72px,10vw,128px)、左右 clamp(20px,4vw,56px)）を表現できない → 本ファイルで上書き
 *  - 見出し英字・本文などのサイズが clamp() 指定できない（fz-* は固定値のみ）
 *  - gap utility に 12px / clamp 値がない
 * 【指定方向不足】
 *  - page-hero--solid に左揃え版がない
 * 【状態不足】
 *  - ボタン hover で背景色をアクセント色にする modifier がない（btn--dark は opacity のみ）
 *  - ナビ現在ページを「項目幅いっぱいの下線」で示す modifier がない
 * 【構造不足】
 *  - sp-nav にヘッダー直下ドロップダウン型がない（フルスクリーン型のみ）
 *  - heading に「番号＋英字＋和文」縦積み型、英字1文字ずつ表示アニメーションがない
 *  - 2カラムを auto-fit grid で折り返す column2 の modifier がない
 *  - フォームの選択肢をボタン型ラジオで並べるパーツがない
 *  - ギャラリー用ライトボックス（Vanilla JS）がない
 * 【装飾パターン不足】
 *  - 見出し右に伸びる細罫線（.sg-ruletitle）
 *  - ヒーロー右側のロゴマーク透かし（mix-blend-mode:multiply）
