/* PRINT — exportación a PDF (window.print / impresión headless)
   Filosofía: el PDF debe verse como el sitio, no como una versión
   despojada. Solo se oculta lo interactivo (nav, sidebar, toggles) y se
   ajusta paginación; el resto del sistema de diseño (colores, acentos,
   degradados, sombras) se conserva tal cual vive en components.css. */
