   1. デザインの方針
   --------------------------------------------------------------------------
   「主催者の手元にいくら残るか」を扱うサイトなので、
   スタートアップ的な華やかさより、検証記事・報告書としての落ち着きを優先する。

   - グラデーションは一切使わない
   - 装飾用のWebフォント・アイコンフォント・等幅ロゴは使わない
   - 色は「インク（濃紺寄りの黒）」＋「深い緑」の2色だけ
     緑は「手元に残る／有利」を表す色として、比較表の最安行と共通で使う
   - 見出しは上に罫線を引く新聞的な処理にする（左に太い縦線を引く定番型は使わない）
   - 角丸とドロップシャドウをほぼ使わず、罫線で構造を作る

   色を変えたいときは、下の変数だけ書き換えれば全体に反映されます。
