 * ======================================
 * 共通SCSSに不足していたもの
 * ======================================
 *
 * 【値の粒度不足】
 *  - fz：11 / 15 / 17 / 26 / 30 / 34px が無い
 *  - pt/pb：140px が無い（最大120）
 *  - gap：8 / 12 / 16 / 28 / 32 / 48 / 56 / 64px が無い
 *  - letter-spacing：0.04em / 0.08em / 0.3em が無い
 *  - line-height：1.25 / 1.7 が無い
 *  - aspect-ratio：16/10・4/5 が無い
 *  - max-width：520px が無い
 * 【構造不足】
 *  - fr比率（5:6 / 4:7 / 6:5）の grid 2カラム（column2 は%固定・gap指定不可）
 *  - 「EN 大 ／ JA 小」を横並びベースライン揃えにする見出し
 *  - 罫線区切りの3カラム／5カラム番号リスト
 *  - 写真上に上部ラベル＋タイトルを載せるカード（card-bnr は角丸・中央/左下配置のみ）
 *  - 定義リスト（dl）の罫線テーブル表現（table-* は table 要素前提）
 * 【装飾パターン不足】
 *  - 斜めにスキューした MORE 矢印
 *  - ボタン末尾の細い横線
 *  - 背景固定（background-attachment: fixed）＋横グラデーション暗幕
 *  - MV の文字せり上がり（マスク＋translateY）演出
 * 【状態不足】
 *  - header__cta の hover を「背景色維持＋opacity」にする手段が無い（共通は $sub_color 背景へ変化）
 * 【その他】
 *  - $base_color をオフホワイトにすると a 要素の文字色が背景と同化するため、a の色を継承に変更
 *
