   Sistema nuevo («mostrador técnico», oct-2026) — tokens y componentes comunes

   Lo comparten todas las páginas del comparador.
   Los componentes van bajo .cmpx. Los tokens --x-* están en tokens.css
   (globales desde el 29-10-2026, cuando migró la cabecera y el pie).
   Ver DESIGN-GUIDE.md.

   Cada página añade su hoja propia detrás (index.css, cmpx-category.css).
   Móvil primero; solo los cinco breakpoints de la guía, en min-width.
