/* ==========================================================================
   FUA Öğrenci Panosu — 4 kolonlu kanban + öğrenci kartı
   --------------------------------------------------------------------------
   Kolonlar: Başvurulacak · Evrak Hazırlığı · Başvuru Yapıldı · Kabul Alındı

   Kolon rengi her sütuna --sc-tone (dolu renk) ve --sc-ink (metin için
   açılmış ton) olarak inline geçilir; kart onu sütundan miras alır.

   NEDEN İKİ TON: istenen #2563EB koyu zeminde 3.91:1 veriyor — dikey
   çizgi/kenarlık gibi metin dışı öğeler için yeterli (3:1), ama 11px
   rozet METNİ için değil (4.5:1 gerekir). Bu yüzden dolgu/çizgi #2563EB,
   rozet yazısı açılmış tonu (#93B4F5, 8.7:1) kullanıyor.
