/* 時読み処 しおり
   手本は『暮しの手帖』のサイト（トップと定期購読のページ。10-04 K「暮しの手帖を完全に再現しましょう」）。
   本文はすべて明朝（手本の秀英明朝は Adobe Fonts なので、しっぽり明朝で代える）。値段と日付だけゴシック。
   色の箱（黄・青・生成り・灰）に、枠線の小見出しを角に重ねる。PC では小見出しを縦書きにする。
   差し色は手本の赤ではなく、鑑定書の PDF と同じ青（10-04 K「赤はやめる」）。屋号はしっぽり明朝 B1 の 800（10-04 K「屋号のフォントがおかしい」で Potta One から替えた）。文字の大きさは手本の 0.875 倍（10-04 K「全体的に文字サイズが大きい」）にしたあと、本文だけスマホ 14px・PC 15px に戻し、12px より小さい文字は作らない（10-04 K「直してください」）。 */
