Why Single-Layer Box Shadows Look Fake

Real-world light sources are area emitters rather than mathematical points. As shadow spreads further from an object, it softens and diffuses naturally. A single-layer CSS shadow produces an abrupt, muddy halo, making UI cards appear flat and artificial.

Physics of Multi-Layer Gaussian Attenuation

By layering between 2 and 6 subtle shadows calculated along an exponential power curve, Lucentool establishes both crisp near-field ambient occlusion and broad ambient diffusion. The result is a luminous, high-end tactile depth.
