/* =========================================================
   業務効率化AI研修 ― AIに仕事を頼める人になる（/ai-training/）2026-10 刷新版
   ・ページ専用。テンプレート page-ai-training.php だけが読み込む（テーマのCSSは来ない）
   ・黒い地に巨大な詰め組みの英字（Inter 850・字間 -0.065em・行ごとに下からせり上がる）＋和文の太字（Noto Sans JP 900）
   ・マザリアルの他ページの見た目（明朝・空のグラデーション）は持ち込まない
   ・すべて .aitr の内側に閉じる。文字は14px未満にしない（C-01）
   ・色は「地の色の組」（.aitr-dark＝気持ちを伝える欄／.aitr-light・.aitr-gray＝事実を書いた欄）で切り替える
