/* ============================================================
   hero-demo.css — Giao diện Hero (thay carousel cũ), phỏng theo
   demo.html: header logo thật + tiêu đề lớn + card phong cách
   tĩnh (đổi ảnh theo tab) + card so sánh Trước/Sau.
   Phạm vi: CHỈ áp dụng bên trong #heroView. Nạp SAU aoc-wow.css.

   TOKEN: dùng ĐÚNG biến của css/tokens.css (--green, --radius-*,
   --shadow-card*, --weight-*, --ink*) — không tự đặt giá trị hex/
   px riêng, để đồng bộ với #appView (đã dùng token này từ trước).
