   EduGuard MOTION qatlami (2026-08-30, egasi so'radi).
   Shablon (New Age) fayllariga tegilmagan — hamma harakat shu yerda.

   Uch qavat:
     1. Reveal — bo'limlar skrollda yumshoq kirib keladi (IO).
     2. Scrollytelling — yopishqoq telefon, 4 bob: har bobda ekran
        almashadi va matn tushuntiradi.
     3. Ambient — skroll to'xtaganda ham sahifa «nafas oladi»
        (hero telefonining suzishi).

   ⚠️ prefers-reduced-motion — birinchi darajali fuqaro: hamma
      harakat o'chadi, kontent DOIM ko'rinadi (animatsiya ortida
      yashiringan matn yo'q).
