   AUTH — barcha kirish sahifalari uchun yagona tizim
   ==========================================================================
   NIMA UCHUN BU FAYL BOR
   2026-09-04 gacha uchta mustaqil shablon bor edi (login.html 429 qator,
   login_role.html 499, student_login.html 548) va ularning ~1480 qatorlik
   inline CSS'i deyarli bir xil edi — 48 ta selektor uchalasida aynan bir xil.
   Farq faqat AKSENT rangida edi: o'qituvchi yashil, rahbar binafsha, operator
   to'q sariq... 7 xil gradient. Bitta mahsulot ettita boshqa saytga o'xshardi.

   Endi hammasi logodagi kobalt ko'k (#0956d8) — public sayt bilan bir xil.
   Rolni RANG emas, IKONKA va nom ajratadi.
