Soft extruded UI where elements appear physically pressed out of the background. Uses paired light/dark shadows of the same background color.
Pioneered by: Alexander Plyuto
Dual box-shadow: one light (top-left) and one dark (bottom-right)
Card and page background share the exact same color (e.g. #e0e5ec)
No borders — shape is defined by shadow contrast alone
Inset shadow variant for pressed/active states
Very low contrast — significant accessibility challenge
Neumorphism works best for these industries
