/* =============================================================
   icd-trial-banner.css — 体験会LP（/icd/trial/）へ送るバナー
   HTMLの原本は scripts/trial-banner.mjs。
   色はLPに合わせる：生成り #f3f1e8 ／ 墨緑 #1e2a22 ／ 葉 #4f6b52 ／ 真鍮 #a98f5c

   注意：このサイトは html{font-size:62.5%}（1rem=10px）。
   素の span/div は 10px で出るので、文字の大きさは全部ここで指定する。
   記事の中では .ic-article a { text-decoration:underline !important } が
   効くので、バナー全体の a はそれより強いセレクタで打ち消す。

   器の幅：トップは約300px、記事の中は約250px（375px端末）。
   スマホは葉を短文の横にだけ置き、見出し・本文・ボタンは全幅にする。
   （葉の列を縦に長く取ると、記事の中では見出しが1文字ずつ折れる）
