📌 Fitur Utama

• Menampilkan gambar dadu sesuai angka yang diacak.
• Gunakan random() untuk menghasilkan angka dari 1 sampai 6.
• Jetpack Compose + Material 3 untuk tampilan UI yang modern.

🔧 Catatan Teknis

• Pastikan gambar dadu (dice_1 hingga dice_6) sudah tersedia di folder res/drawable.
• Tombol "Roll" mengambil string dari file strings.xml.
