   hp-chrome.css — お申し込みのページ（signup.html）に付ける、ホームページと同じヘッダーとフッター（2026年11月3日・ご本人）
    ご本人「https://app.welconvo.com/signup.html のページにヘッダー、フッターがついていません」。
    ホームページ（Ainova-hp）の .nav・.site-footer と同じ見た目を、名前を分けて（hp-）ここに写した。
    ホームページの CSS をそのまま読むと、明るいお申し込みのページの見た目（body・h1・h2 など）まで変わるため。
    ★ホームページのヘッダー・フッターを直した時は、ここも合わせる（大きさ・色は手元のホームページで測った値）。
    ★チャットの中に開いた時（枠の中）は出さない（signup.js が html に in-frame を付ける）。
