/* หน้าเว็บ หลอมทองพระสมุทรเจดีย์ — โทนแดงครั่งกับทอง ทางการ หรู เรียบ
   แดงเข้มคือสีแบรนด์ของร้าน (ป้ายหน้าร้าน โลโก้) ทองใช้เป็นสีเน้นเท่านั้น ไม่ราดทั้งหน้า
   พื้นหลักเป็นงาช้างอุ่น ให้ส่วนพื้นแดงเป็นจังหวะคั่น ไม่ใช่พื้นดำทั้งเว็บ
   กฎเหล็ก: ทุกส่วนต้องยังสวยเมื่อลูกค้าใส่ข้อความสั้นมากหรือยาวมาก และต้องไม่ล้นจอที่ 360px */
