/* ============================================================
   サウナ販売（/sauna 以下）— 2026-10-29 旧STUDIO（sauna.n-o-e-l.com）から移設
   ・販売業者は大三工事株式会社。Noël の宿のページとは別の見た目（旧サイトの白×水色・細いゴシック）
   ・書体：旧サイトの New Rodin / Helvetica Now（STUDIOの有料書体）の代わりに Noto Sans JP / Inter
   ・色：旧サイトの水色 #4bbebb は白地で文字に使うと薄すぎる（2.2:1）ので、
     文字には濃い水色（--sn-ink 4.8:1）、大きな英字の見出しだけ中間の水色（--sn-teal-d 3.2:1・大きな文字の基準3:1）を使う
   ・site.css の上に重ね、body.sn の中だけに効かせる。フォームの部品（.form-field など）は site.css のものを色だけ替えて使う
   ============================================================ */

/* site.css は画面幅1025px以上で body に左サイドバーぶんの余白（padding-left: var(--side-w)）を取る。
