5️⃣ THAM KHẢO GIAO DIỆN

Tất cả các component đều sử dụng:

• Các class Tailwind CSS trực tiếp (không dùng CSS module)
• Breakpoint responsive: md:, lg:
• Chế độ tối: Dùng biến CSS trong globals.css
• Mẫu component: Card → CardContent

Các mẫu khoảng cách thông dụng:

// Các phần
<section className="py-16 md:py-24">
  <div className="mx-auto max-w-7xl px-4">
    {/* nội dung */}
  </div>
</section>

// Card
<Card>
  <CardContent className="p-4 md:p-6">
    {/* nội dung */}
  </CardContent>
</Card>

// Lưới
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
  {/* các phần tử */}
</div>
