/* =============================================================
   購入画面（purchase.html）の新しい見た目（2026-10-27 購入画面の作り直し フェーズ1）
   運営者「よりモダンで安心でき、申し込みしやすい設計に」。色と形はフロント（assets/front/css/modern.css）と
   スマホのメニューにそろえる。
   ・上の帯（.bp-hero）と手順の表示（.bp-steps）＝全部のステップ
   ・プランを選ぶ画面（.bp-s1）＝かんたんシミュレーション・主なプラン 3 つのカード・ほかのプラン（畳む）・
     ご注文の内容（パソコンは右の欄・スマホは一覧の下）・画面の下の帯（スマホ・タブレット）
   HTML は js/purchase.js の renderStep1（文言は辞書の buy）。ステップ 2・3（フェーズ2）・4＝完了の画面（フェーズ3）もこのファイルの後ろの方
   ★手順の表示の .steps・.step-item は長期滞在のページ（subscription.html）と共通の見た目（style.css）なので、
     ここでは .bp-steps の中だけを直す
