   header-footer2026 — 新ヘッダー／フッター（2026 リニューアル）
   header-2026.php / footer-2026.php 用。すべて .hf- で名前空間化。
   既存 style.css の a / a:hover / a:hover img は :where() で同じ詳細度にして後勝ちで上書きする
   （.hf-xxx:hover などの部品側の指定が負けないように、土台の指定は詳細度を上げない）。
   読み込み順: design-tokens.css → このファイル。配色は --mmi-*。
     白地の金文字 … --mmi-gold-ink（純白の上だけ）
     紺地の金文字・飾りの線・金の地（文字は紺） … --mmi-gold
   ブレークポイント: 1200 / 940 / 768 / 568。無条件がデスクトップ、@media not all and (min-width: N) で狭い側。
