/* 合同会社Nexas 共通スタイル（生成り×墨・C案）
   配色・書体・余白の基準値（:root の変数）はこのファイルだけで定義する。
   各ページの <style> には、そのページ固有の部品だけを置く。

   色の使い分け（変えるときはここを読む）
   - paper     … ページの背景
   - porcelain … カード・交互の章の明るい側
   - ink       … 本文・見出し・主ボタンの面
   - coal      … 濃い帯・想いの章・CTA・フッターの背景
   - clay      … 小さい強調文字・リンク・キッカー
   - saffron   … 線・大きな数字・濃い背景の上の文字だけ。薄い背景の上の小さい文字には使わない（明るさの差が足りない）
   - teal      … 予備。原則使わない
   書体: h1・h2 だけ Noto Serif JP（明朝）。それ以外は Noto Sans JP、英数は Inter。 */
