/**
 * CUSTOM CSS - POWER GATE
 * ========================
 * Estilos personalizados siguiendo las Golden Rules de Bootstrap:
 * - NO sobreescribir resets de Bootstrap innecesariamente
 * - Usar variables CSS para colores de marca
 * - Extender componentes de Bootstrap, no reinventarlos
 * - Mantener especificidad baja (evitar !important)
 * 
 * ESTRUCTURA:
 * 1. Variables CSS
 * 2. Tipografía base
 * 3. Utilidades personalizadas
 * 4. Componentes extendidos
 * 5. Animaciones y transiciones
 * 6. Responsive (si es necesario)
 * 
 * CÓMO EXTENDER:
 * - Agregar nuevas variables en :root
 * - Usar clases de Bootstrap como base
 * - Añadir estilos específicos solo cuando sea necesario
