/**
 * Archivo principal de Estilos CSS.
 * 
 * BENEFICIOS DE ESTA ARQUITECTURA (Separación de Preocupaciones):
 * 1. Mantenimiento: Separar HTML y CSS permite cambios globales de diseño desde un solo archivo.
 * 2. Rendimiento y SEO: El archivo CSS externo se guarda en caché por el navegador del usuario.
 *    Esto reduce el peso del HTML (First Byte más rápido) mejorando la velocidad de carga (LCP),
 *    lo cual es fundamental para el SEO.
 * 3. Escalabilidad: Es posible incorporar posteriormente preprocesadores (SASS/LESS) u organizar
 *    por componentes en la carpeta sin alterar el marcado HTML original.
