/**
 * Landing page styles.
 *
 * RÀNG BUỘC:
 * - Màu theo vertical (windows/bath/roof/solar/hvac) lấy từ DB, đổ vào CSS variable
 *   trong Blade. KHÔNG hardcode mã màu từng vertical trong file này.
 * - Responsive: breakpoint 880px như landing mẫu.
 *
 * CÁCH DÙNG BIẾN VERTICAL:
 *   Blade set --v / --v-light / --v-contrast trên phần tử bọc (xem layouts/landing).
 *   File này chỉ tiêu thụ biến, không bao giờ biết vertical nào đang chạy.
