/*
 * icons.css — Sistema unificado de iconos Lucide (SVG inline)
 *
 * Reemplaza los emojis Unicode de la landing por SVGs vectoriales.
 * Los SVG se insertan inline en el HTML (no usamos el script runtime
 * de Lucide). Este CSS solo define tamaños, colores via currentColor,
 * y animaciones de entrada.
 *
 * Patrón de uso:
 *   <span class="ig-icon ig-icon-lg" aria-hidden="true">
 *     <svg viewBox="0 0 24 24"> ... paths Lucide ... </svg>
 *   </span>
