/* 
 * TEMPLATE CLÁSICO V3.0 - PÁGINA DE PRODUCTO
 * Diseño tradicional con colores claros y profesionales
 * Variables CSS del sistema: --main-color, --main-color2, --main-color3
 * --secondary-color, --accent-color, --text-muted, etc.
 * 
 * 🚨 IMPORTANTE - CONTENEDOR CON FONDO BLANCO GLOBAL 🚨
 * La clase .container global tiene background: white por defecto.
 * Este template CONTRARRESTA ese fondo usando background: transparent
 * en las secciones y utiliza fondos diferenciados para crear contraste.
 * 
 * ESTRATEGIA DE CONTRASTE MEJORADA:
 * - Secciones principales: background: transparent (usar el blanco del container)
 * - Items individuales: background: white con bordes #d1d5db para máximo contraste
 * - Textos principales: #0f172a (negro slate) para máxima legibilidad
 * - Textos secundarios: #475569 (gris oscuro) para jerarquía visual clara
 * - Shadows: Más pronunciados (0 4px 12px rgba(0,0,0,0.15)) para separación visual
 * - Hovers: Colores primarios del sistema con transiciones suaves
 * 
 * BARRA DE SEGURIDAD - ALTO CONTRASTE:
 * - Container con background: transparent !important para contrarrestar el blanco global
 * - Items con fondo blanco y bordes grises visibles para máximo contraste
 * - Badges con fondo blanco y shadows pronunciados para destacar
 * - Textos muy oscuros (#0f172a) para legibilidad óptima
 * - Hovers con colores primarios para interactividad clara
