   本国 formthotics.com/nz_en と同じ見た目の共通部品（Issue #5・2026-11-05）
   style.css（旧テーマ）の後に読み、全ページの土台・ヘッダー（masthead）・パンくず・ボタン・
   見出しラベル・左右 2 分割のパネル・カード・フッターを本国の寸法にそろえる。
   寸法は 2026-11-05 に本国のページ（幅 1440px）を実測: 余白 96px・パネル角丸 8px・パネルの外側 16px・
   h1 57px/500・h2 40〜45px/400・本文 16px・ボタン 14px 大文字・角丸「22px 6px」。
   書体は本国の Graphik の代わりに Noto Sans / Noto Sans JP（オーナー指定）。
   ページ固有の部品はそれぞれのテンプレートの <style> か、ここの「ページの部品」に置く。
