/* 誘導管理アプリ（FunnelMaster）の見た目（2026-10-23 作り直し。主人の指示「もうちょっと2026年っぽくイケてるデザインに」）
   - 広い画面では、メニューを左の縦の帯（サイドバー）にする。狭い画面では、今までどおり上の帯
   - 色は、落ち着いた灰色（zinc）を地に、藍（インディゴ）〜紫を差し色にする。端末がダークモードなら暗い配色に自動で切り替える
   - 角は大きめに丸め、影は薄く重ねる。数字は桁をそろえる（tabular-nums）
   - マスタ表だけは「シートと同じ見た目」（spec.md 5章）なので、ダークモードでもシートの色のまま
   - 画面の安全の設定（CSP）で外部のフォント・画像は読めないので、端末の日本語フォントと、data: の SVG のアイコンを使う
   - 画面の部品の名前（class）は、前の版から変えていない（JavaScript はそのまま） */
