/*
 * AIOROS - Hoja de Estilos Principal
 *
 * Sistema visual "centro de control" (ver DESIGN.md del proyecto):
 *  - Lienzo negro puro y UN solo color de primer plano (#f0f0fa).
 *  - Tipografía: Inter (texto) y JetBrains Mono (etiquetas), en mayúsculas con tracking 0.09–0.10em
 *    para menú, etiquetas, botones y texto; 0.02em en titulares.
 *  - Botones siempre con contorno de 1px, sin relleno, radio 4px.
 *  - Cero elevación: sin sombras, sin degradados decorativos, sin blur.
 *    Las únicas transiciones de color son los fundidos a negro sobre fotos.
