     Index.php'ye baktığımda header içinde btn-ghost "Ara" ve btn-primary "WhatsApp" var.
     Kullanıcı menüyü iptal ettiğine göre, mobilde headerda bu iki butonun görünmesi lazım.
     Ya da sadece WhatsApp ikonu ve Ara ikonu şeklinde mi?
     Mevcut CSS'te .btn px/py değerleri var. Mobilde çok yer kaplayabilir.
     Şimdilik butonları görünür yapalım, sığmazsa küçültürüz.
