/* ============================================
   Momentary トップページ(index.php)専用スタイル

   構成の考え方:
     - スマホ表示を基準(ベース)にデザインし、
       PC/タブレット幅(900px以上)になったら、
       コンテンツ自体は "スマホ相当の幅の中央カラム" のまま、
       左右に「ロゴ(左)」「メニュー(右)」だけの装飾レールを
       追加する、という最近よく見るレイアウト。
     - 配色はカスタマイズ画面のデフォルトテーマ(テラコッタ×ゴールド)を
       踏襲し、絵本の世界観とサイト全体の一体感を出している。
