/*
  台湾 旅のしおり — デザイン方針
  ・スマホで見るのが前提（PC は編集時に確認するくらい）。
    中身は最大 480px 幅の1カラムで、PC でもスマホと同じ見た目を中央に置く
  ・移動は画面下のナビ（親指が届く位置）。日程タブはスクロールしても上に貼りつく
  ・色は台湾の街の色を「やわらかく」したもの：
    珊瑚色（提灯・廟の朱をパステル寄りに）、淡い金、翡翠の緑、生成りの紙
    強い赤の面は使わず、塗るのはヒーローとアクセントだけ
  ・セクションは「紙」と「うすい翡翠（.sec-tint）」を交互に
  ・見出しに添える漢字（.sec-zh）は繁体字。区切りの帯（.fret）は回紋
