/* ==========================================================================
   AI Heartland — BRUTUS準拠の誌面（シゴトのホント／Cloudory と同じ意匠の系統）
   純白 #ffffff × 漆黒 #101010、雑誌グリッド、重い見出し、トピック（クラスタ）カラー、
   暗色帯 #191919、英字＋和文の対訳キャプション、角は四角・罫線で区切る。
   商用フォント不使用: 本文=Noto Sans JP / 見出し=Zen Kaku Gothic New / 英字=Jost / コード=JetBrains Mono。

   - 色の単位は「トピック（_data/clusters.yml の id）」。記事は tags の先頭一致でトピックが決まる。
     --cat-<id> を足すときは tools/visual/brand.mjs の CATS と _data/clusters.yml の color も同じ値にする。
   - 動きは assets/js/site.js が付ける .motion / .is-in で出す。動きを減らす設定の人には出さない（末尾の品質フロア）。
   - 記事本文（_posts）は書き換えない。過去記事が使っている装飾クラス（point-box・box-tip・marker-yellow …）は
     「本文の装飾（旧記法の受け皿）」でこの意匠に寄せて受け止める。
   - このファイル1枚だけ。ページや include に <style> を書かない。
