   Ilgari animatsiyalar sahifalar bo'ylab tarqoq edi: har sahifa o'z
   `transition: all 0.2s ease` ini yozardi, natijada bosish va olib
   borish sezgisi joydan joyga farq qilardi.

   Bu yerda yagona lug'at bor:
     · davomiylik va yumshatish tokenlari
     · kirish animatsiyalari (.ss-rise, .ss-stagger)
     · o'zaro ta'sir (.ss-lift, .ss-press)
     · yuklanish holati (.ss-skeleton)

   Barcha harakat `prefers-reduced-motion` ostida o'chadi — bu shart,
   chunki animatsiya ba'zi foydalanuvchilarda bosh aylanishiga sabab
   bo'ladi.
