/**
 * CARDS UNIFIED - Clean Architecture
 * ===================================
 * 
 * ÚNICA FUENTE DE VERDAD para TODOS los cards del proyecto
 * 
 * PRINCIPIOS:
 * 1. Componente base .card con estilos compartidos
 * 2. Variantes específicas solo modifican diferencias
 * 3. Sin !important (especificidad natural)
 * 4. Valores consistentes (8px radius, -2px hover)
 * 5. Variables CSS para todo
 * 
 * ESTRUCTURA:
 * - Base Card (común a todos)
 * - Content Cards (blog, artículos)
 * - Feature Cards (características, herramientas)
 * - Dashboard Cards (stats, sidebar)
 * - Info Cards (valores, equipo)
 * - Auth Cards (login, register)
