/*
 * solutions_ · Base común de las infografías interactivas
 * --------------------------------------------------------
 * Todas las infografías de public/interactivas/infografias/ cargan este archivo
 * y _base/infografia.js. Aporta:
 *   - Tipografía (Inter), colores de marca y tema claro/oscuro.
 *   - Barra de marca (logo solutions_) y pie con la dirección de la infografía.
 *   - Componentes para infografías nuevas: secciones, desplegables, pilas de
 *     capas, tablas, recuadros y modo «sencillo / técnico».
 *   - Modo exportación (?exportar=1): todo desplegado, sin botones, listo para
 *     generar la imagen PNG y el PDF con «make infografias».
 * Guía de uso: docs/MANUAL.md → «Infografías».
