/*
  Fujimoto Rheuma Portal — メインCSS
  B案「Teal＋アプリコット」(Top-B-Teal.dc.html) を視覚仕様として、
  style-hover等のランタイム依存を排したセマンティックCSSで再実装したもの。

  設計方針：モバイルファースト。
  ベース= 767px以下（1カラム基本）
  768px以上  … 2カラム系グリッドを解禁（4つの入口など）
  1024px以上 … PCの主要2カラムレイアウト（ヒーロー・アコーディオン・監修者）を解禁
  1440px以上 … コンテナ最大幅1200pxで中央寄せ・余白拡大

  横スクロールを発生させないため、固定 width ではなく max-width + 100% を徹底する。
