/* 案件郵便 サービス紹介（広告用 LP）— 2004〜2005年ごろのポップなレンタルサーバーのトップページの作法をまねたパロディ。

   黄緑の星柄の地に白い箱 / 黒い帯の仕様一覧 / 斜めのパステル縞の看板と白フチの傾いた題字 / ピンクのタブ /
   水色の現在地の帯 / 本文と右列の2段組 / 色違いの正方形タイル 4×2 / LED 風の数字 / 帯の見出し /
   STEP 1→2→3 / 銀色の丸いボタン / 橙帯のお知らせ / 足元の提携バナー列と推奨ブラウザ。
   文字と地の明暗比は 4.5:1 以上（白フチの題字は、フチと地の両方で読める色にしている） */
