/* ==========================================================================
   CADCENTER — main.css (theme WordPress)
   Một file CSS duy nhất cho toàn site. Không dùng framework.
   Thiết kế mobile-first: style mặc định cho điện thoại,
   @media (min-width: …) bổ sung cho màn hình lớn hơn.

   Mục lục
   1. Biến màu, font, khoảng cách (design tokens)
   2. Reset & nền tảng
   3. Tiện ích (container, skip link, sr-only)
   4. Header & menu
   5. Hero slideshow
   6. Lối tắt (4 ô điểm mạnh)
   7. Section + carousel thẻ
   8. Trang mục (danh sách sản phẩm)
   9. Footer
   10. Thanh liên hệ cố định (mobile)
   11. Giảm chuyển động
