/* =====================================================================
   BOSS International School — komponentlar (Swiss / xalqaro uslub)
   ---------------------------------------------------------------------
   Uslubning uchta qoidasi butun fayl bo'ylab amal qiladi:

     1. Tuzilma SOYA bilan emas, CHIZIQ va BO'SHLIQ bilan chiziladi.
        Shuning uchun --shadow-1/2 = none, radius esa deyarli nol.
     2. Tipografika asosiy vosita. Ierarxiyani rang emas, o'lcham va
        bo'shliq beradi (vault: "interfeysning 90% i — matn").
     3. Bitta accent. Brend ko'ki faqat amalga chaqiruvda va faol holatda;
        qolgan hamma narsa neytral. Amber logotipda qoladi.

   Ichma-ich selektorlar 2 darajadan oshmaydi, hardcode hex yo'q,
   !important ishlatilmaydi (vault: 05 - CSS arxitekturasi).
