   Nguồn: zip "website KQT.COM (8).zip" → flatsome/{FLATSOME_BUILD_WARRANTY.md,
   PROMPT_CLAUDECODE_WARRANTY.md, chinh-sach-bao-hanh.html, kqt-warranty.css,
   kqt-warranty.js}. Cùng kiến trúc 4 trang trước (Dịch vụ/Giới thiệu/Liên hệ):
   mọi selector SCOPE dưới body.kqt-bh — không đụng .section/.eyebrow toàn cục
   (Flatsome đã có .section{padding:30px 0} riêng, đụng vào là tràn layout
   sang mọi trang khác — xem cảnh báo trong kqt-service.css).
   H1/H2/eyebrow/lead dùng CHUNG biến --fs-h1-page/--fs-h2/--fs-eyebrow/--fs-lead
   từ kqt-typography.css (nạp unconditional mọi trang) thay vì tự khai clamp()
   riêng — quyết định đã chốt từ Đợt 2 chuẩn hoá cỡ chữ toàn site (2026-09-10).
