/*
 * DİKKAT: Kategori kartlarındaki Font Awesome ikonlarını CSS ile değiştirmek,
 * HTML'de direkt Font Awesome class'ları basıldığı için (örn: <i class="fas fa-utensils">)
 * standart CSS ile doğrudan ve güvenilir bir şekilde yapılamaz.
 *
 * Eğer ikonları kategori ismine göre değiştirmek istiyorsanız:
 * 1. En doğru yol: Veritabanındaki 'kategoriler' tablosuna 'icon_class' gibi bir sütun ekleyip,
 * admin panelinden her kategoriye ilgili Font Awesome ikon class'ını (örn: 'fa-glass-martini-alt', 'fa-beer') kaydetmek.
 * Sonra index.php'de bu class'ı dinamik olarak <i class="fas <?php echo $category['icon_class']; ?>"></i> şeklinde basmak.
 * 2. Geçici CSS hilesi (standart dışı, her tarayıcıda çalışmayabilir):
 * category-card h3:contains("ALKOLLÜ İÇECEK") + .category-icon-placeholder::before { content: "\f005"; font-family: "Font Awesome 5 Free"; font-weight: 900; }
 * Bu tür bir yaklaşım, :contains() pseudo-class'ının standart olmaması ve metin içeriği değişirse bozulması gibi dezavantajlara sahiptir.
 *
 * Bu birleştirilmiş CSS dosyasında bu tür spesifik Font Awesome ikon değişikliği kuralları yer almamaktadır.
 * Eğer bu özelliği istiyorsanız, PHP tarafında dinamik ikon ataması yapılması önerilir.
