/* ===== スマホ用の追従CTA =====
   SPは全長7,200px超で申込フォームが86%地点にあり、FV直下のCTAを過ぎると
   最下部までCTAが無かった。中盤からでも申込へ飛べるようにするための追加。

   既存への影響を避けるための方針：
   ・PC（861px以上）では display:none のまま。既存レイアウトに一切触れない
   ・position:fixed なので通常フローに影響しない（body等の余白も変更しない）
   ・フォーム到達時に消える制御をJS側で行うため、フッターや送信ボタンを覆わない
   ・既存のz-indexは hero-overlay の -1 のみなので、60で衝突しない */
