/*
 * DHTD Child — microsoft-365.css (Task 60A, 02/10/2026)
 * CSS riêng cho Page "Microsoft 365" (/microsoft-365/) — chỉ enqueue trên đúng
 * Page này (is_page('microsoft-365'), xem inc/enqueue.php). Dùng token màu
 * (brand-colors.css), token spacing Task 54 và utility chung của main.css
 * (.dhtd-container/.dhtd-eyebrow/.dhtd-section-title/.dhtd-btn*). Không định
 * nghĩa lại những thứ đã có; không sửa main.css/home.css/about.css.
 * Gold chỉ dùng cho CTA, badge và viền highlight. Không shadow nặng.
