 * PLOW & GROW — style.css
 * Theme "cartoon nông trại" đồng nhất:
 *  - Thẻ kem-gỗ viền nâu dày + bóng đổ cứng (chunky, như board game)
 *  - Chữ nâu đậm trên nền kem; tiền/giá luôn màu hổ phách
 *  - Nút mọng kiểu 3D (mép dưới đậm, ấn lún xuống)
 *  - Cỡ LỚN: mục tiêu chạm >= 52px, chữ chính 30px+
