   Capa de diseño del portfolio (se aplica encima de styles.css).
   Papel cálido + tinta, un acento cobalto y un coral reservado para pequeños
   gestos (subrayado del titular, viñetas, progreso). Titulares en Bricolage
   Grotesque, texto en Manrope.
   Tema claro por defecto. El oscuro solo existe bajo [data-theme="dark"], que
   fija js/theme.js cuando la visita lo elige: ya no se sigue al sistema.
   Capas: navegación 20, skip link 30, progreso 40.
