/**
 * diseno.css — Sección "Diseño de producto" de la portada (template-parts/product-design-section.php).
 *
 * Un plano de ensamble claro en medio de la portada oscura: texto que avanza a
 * la izquierda y el producto fijo a la derecha, con pestañas por rubro arriba
 * del plano. Naranja solo para las piezas en foco y los acentos.
 *
 * Sin JS o sin WebGL la sección queda en .is-static: los cuatro rubros se
 * muestran uno debajo de otro, sin plano.
 *
 * Requiere que ningún ancestro tenga overflow hidden/auto (rompe position: sticky);
 * la portada usa overflow-x: clip en impresion.css.
