/**
 * Promo Card Styles — Product Card Style
 *
 * Layout: Giống product_card.html với khác biệt:
 * - Nút "Mua ngay" cam (thay vì "Thêm vào giỏ" xanh)
 * - Progress bar kích thích mua hàng (trên nút)
 * - Discount badge trên ảnh
 * - Không có stock status badge (promo luôn có hàng)
 * - Section-level countdown timer
 *
 * CSP Compliant — Không inline styles
