   Kurgu: koyu "gece mavisi" çerçeve (üst şerit, başlık, ana sayfa giriş alanı, iç sayfa başlıkları, alt bilgi) + okunaklı açık içerik alanları.
   Renkler: camgöbeği (#22d3ee) -> çivit (#6366f1) -> mor (#a855f7) geçişi yalnızca süsleme için; açık zeminde metin, bağlantı ve
   düğmelerde koyu çivit (#4f46e5, beyaz üzerinde 6.3:1, WCAG AA). Kurumsal kimlik gelince :root içindeki değişkenlerden değiştirilir.
   Yazı tipleri (kendi sunucumuzdan): Montserrat başlık, Source Sans 3 gövde; etiket ve saatlerde sistemin eş aralıklı yazı tipi. */
