 * 「Dr.前島の膠原病論」series の記事にだけ enqueue される（mu-plugins/mrc-learning-map.php）。
 * selector はすべて site-owned prefix .mrc-learning-map* 配下。global の ol／li／.card／.step は触らない。
 * JS・animation・外部 font・外部 icon なし。矢印は border で描く装飾（text を持たないため読み上げ対象外）。
 * layout は mobile-first の 1 column。container query で本文幅に応じて横並び（未対応 browser は 1 column のまま）。 */
