 * Futari Connect — 匿名掲示板（2ちゃんねる・5ちゃんねる風）のスタイル。

 * 並び方は2ちゃんねるにそろえている。
 *   掲示板の名前 → ローカルルール → スレッド一覧（タイトルと件数）→ 各スレッドの要約 → スレ立て
 *   スレッドは「番号 ：名前：日時 ID:xxxxxxxx」の見出しと、一段下げた本文の繰り返し。
 *
 * 色は2種類。設定の「見た目」で切り替える。
 *   .fbbs--classic … 2ちゃんねるらしい灰色の地と緑の名前（既定）。
 *   .fbbs--site    … サイトの主色（SWELL の --color_main）になじませた落ち着いた配色。
 *
 * SWELL の本文用の見出しやリストの飾りが乗らないよう、すべて .fbbs 配下で打ち消している。
