 * 旧テーマ（arkfarm_since_240213）の詳細レイアウト（activity / event 共用）
 *  2026-07-07 以前公開の activity・event に適用する（旧 single-activity / single-event 共通の #participation-single-container 構造）。
 *  旧 style.css から participation-* / custom-wysiwyg / calendar を抽出。
 *  ※ calendar-* は activity のみ使用（event は状態分岐＋ボタンのみでカレンダー無し）。
 *  ※ サイドバー / 下部共通セクション / GSAP は再現対象外。
 *  ※ 旧記事は今後更新しないため SCSS ソースは持たず、このファイルを直接管理する。
 *  ※ 旧テーマは html:62.5%(1rem=10px) だったため、font-size の rem は px に変換して固定。
 *  ※ 申込ボタンは旧テーマの共通btnシステム＋外部SVG依存のため、同等見た目を自己完結で再現。
