/* ナビ：PC の左の帯／狭い画面の下のタブバー・ページ上部のタブ・⌘K */

/* ============================================================
   ナビ（5つの大分類）
   ------------------------------------------------------------
   PC は左の細い帯（大分類）＋ページ上部のタブ（画面）＋切り替え（見方）、
   狭い画面は同じ帯を下のタブバーに置き換える（同じ要素＝頭の中の地図が1つ）。
   以前は20行のサイドバーにサブメニューが開閉し、低い画面では下の設定が押し出されていた。
   中身は js/nav.js の NAV から描く。
