/* ========================================
   TimeClub — Premium Dark Theme Stylesheet
   ========================================

   BU FAYL NIMA QILADI:
     Saytning barcha vizual ko'rinishi shu CSS fayl orqali boshqariladi.
     Dark (qorong'i) tema asosida qurilgan, zamonaviy dizayn.

   TUZILISHI (yuqoridan pastga):
     1. Google Fonts    — Shriftlarni internet orqali yuklash
     2. CSS Variables   — Ranglar, o'lchamlar, animatsiyalar uchun o'zgaruvchilar
     3. Reset & Base    — Brauzer standart uslublarini tozalash
     4. Utility Classes — Ko'p ishlatadigan yordamchi klasslar
     5. Animations      — Animatsiya kalit kadrlari (keyframes)
     6. Components      — Tugmalar, navbar, kartalar va h.k.
     7. Sections        — Har bir sahifa bo'limi uchun uslublar
     8. Responsive      — Mobil qurilmalar uchun moslashuvlar

   MUHIM TUSHUNCHALAR:
     - CSS Custom Properties (--accent, --bg-primary va h.k.) —
       Bu o'zgaruvchilarni o'zgartirsangiz, butun sayt ranglari o'zgaradi
     - .reveal, .reveal-left — Scroll animatsiya klasslari.
       JS da IntersectionObserver "active" klassini qo'shadi
     - Glassmorphism — Shaffof fon + blur effekti (zamonaviy dizayn uslubi)

     2. Foydalanuvchi pastga scroll qilib, element ekranga kirganda
        JS (IntersectionObserver) "active" klassini qo'shadi
     3. CSS .reveal.active → elementni silliq paydo qiladi (opacity:1)

   Turlari:
     .reveal       — Pastdan yuqoriga paydo bo'ladi
     .reveal-left  — Chapdan o'ngga paydo bo'ladi
     .reveal-right — O'ngdan chapga paydo bo'ladi
