   Rin Blog — main.css

   読者の大半はスマホ。スマホの表示を基準に書き、画面が広いときだけ段組みや余白を足す。

   文字の方針
   - 和文も欧文も端末の書体（ヒラギノ角ゴ / Noto Sans JP）。飾りの書体は使わない
   - 本文は 17px・行間 1.9。補助の文字も 13px 未満にしない。灰色は背景とのコントラスト 4.5:1 以上
   - 等幅の書体はコードだけ。日付や数字は本文の書体のまま桁をそろえる（tabular-nums）

   配色
   - 既定はベージュの紙色。端末のダークモード設定には従わず、ヘッダーの切り替えで選んだときだけダークにする
   - ダークは真っ黒にせず、温かみのある濃い灰褐色にする
   - 色はアイキャッチのジャンル色だけ。アプリ・ゲームへの入口だけポータルの青緑を使う
