/* Kariyer Platformu — tasarım sistemi
 *
 * Referans: rezi.ai (kullanıcı tarafından örnek olarak verildi).
 * Ondan alınan ölçülen değerler:
 *   · Gövde 17.6px / zemin #FAFAFA
 *   · Başlıklar MEDIUM (500) — bold değil. Büyük punto + ince ağırlık,
 *     "kalın her yerde" görünümünden kaçınır; asıl profesyonel duruşu bu verir.
 *   · Harf aralığı başlıklarda negatif (-0.02em)
 *   · Butonlar tam yuvarlak (pill)
 *   · Vurgu mavisi (WCAG icin koyulastirildi — asagida)
 *
 * PP Neue Montreal ticari bir yazı tipidir; en yakın ücretsiz karşılığı
 * Instrument Sans kullanıldı.
