/* ==========================================================================
   Tokyo Tech Week 公式イベントカレンダー
   配色はモノクロ（2026-10-13 Daimu指示）: 白地＋墨 #101820＋グレーの段階だけ。色を持つのは立体アイコンだけ（差し色は外した）。
   - 本家 hosts.tech-week.com には寄せすぎない。アクセントは墨の線・面と「路線図」風の区切り線（.grad_rule）で出す
   - 暗い帯の上のアクセントは白（--accent-on-band）。フォーカス枠は白地・墨地どちらでも3:1を超えるグレー
   - 欧文の見出し・数字はロゴと同じ Archivo（幅を詰めた太字）。和文は端末の書体
   - 余白は4pxグリッド
