   タイポグラフィの方針（日本語を、きれいに組む）
   ・見出し：Zen Kaku Gothic New（太字）＋ palt（プロポーショナルな字詰め）＋ わずかなマイナスの字間
   ・本文：Noto Sans JP、行間は広め（1.95）、字間はほんの少し広げる。長い文章に palt は使わない
   ・数字・英字：Inter（等幅ではなく、見出し用に字間を詰める）／ {{role}} のような記号：JetBrains Mono
   ・改行：text-wrap: balance / pretty、line-break: strict、word-break: auto-phrase（文節で折る）。
     見出しは、意味のかたまり（.nb）が途中で割れないようにして、改行の位置を決める
   ・約物：text-spacing-trim（行頭のカッコ・句読点の余白を詰める）、text-autospace（和欧文の間のすき間）
