   Moa — styles
   Visual language: photography first, chrome recedes, one accent
   blue. Type: Pretendard Variable (SIL OFL 1.1, vendor/pretendard). Motion and feel: Emil Kowalski's
   design-engineering rules —
     · custom curves, never ease-in; UI motion ≤ 300ms, drawers ~400ms
     · exits faster than entrances; transitions (interruptible) over keyframes
     · only transform / opacity animate; never from scale(0)
     · every pressable gives :active feedback; hover only on real pointers
     · reduced motion keeps fades, drops movement
