/**
 * Claymorphism Design System v3.0
 * Pure Claymorphism - Inflated, Fluffy 3D UI
 * 
 * Based on official claymorphism principles:
 * - https://codeadrian.github.io/clay.css/ (Adrian Bece)
 * - https://hype4.academy/tools/claymorphism-generator (Michal Malewicz)
 * 
 * Key Characteristics:
 * - NO hard offset shadows or dark drop shadows
 * - Inner highlight (white/light at top)
 * - Inner shadow (color-tinted at bottom-right)
 * - Soft colored ambient glow (matching element color)
 * - Very rounded, inflated shapes
