   HVSC – Công nghệ: 3 trang dịch vụ Email doanh nghiệp / Chứng chỉ SSL / Hoá đơn điện tử (13/10/2026)
   Nạp SAU pillar-tech.css bởi mu-plugins/zz-hv-dv-cong-nghe.php, chỉ trên 3 trang này (body.hv-dv-email|ssl|hddt).
   Mỗi trang 1 màu nhấn riêng (teal / hổ phách / cam đất) + khối minh hoạ riêng; vẫn dùng ngôn ngữ kỹ sư của trụ.
   Sáng/Tối: theo html[data-theme]; khung minh hoạ giữ tối đặc như .pt-term.
