/* 第28号 甕覗舎(架空・藍染の工房)— 組版の決め
   見出し=游明朝 / 本文=游ゴシック。**主色は藍1色**。ただしこの店の商品は藍そのものなので、
   藍を12段に割った目盛り(--ai-01 〜 --ai-12)を色の体系として持つ。罫・釦・強調は --ai(第7段)だけ。
   地は「生成り」ではなく、晒す前の木綿に近い温かい灰白(#f2efe8)。
   直近の地色: 024=生成り / 025=濃紺 / 026=冷たい白+藍 / 027=石膏の灰 → 026と近くならないよう、
   地を温かい側へ振り、藍は「面」ではなく「12段の目盛り」として使う。
   余白・字送りの刻みは design-system/028-shoudousha/MASTER.md の spacing を下敷きにしている
   (Portfolio Grid + Exaggerated Minimalism。書体だけは端末内蔵のものへ差し替え。外部フォントは禁止)。 */
