   ARQUITECTURA DE SUPERFICIES
   Los componentes no usan colores fijos: leen variables semánticas
   (--surface, --text, --line, --accent…). :root define la superficie clara.
   Las secciones oscuras (.px-bg-ink) sólo redefinen esas variables, así que
   tarjetas, etiquetas, listas y enlaces se adaptan solos sin reglas duplicadas.

   Proporción del manual de marca: 80 % crema/lino · 10 % tinta
   · 7 % salvia · 3 % durazno.
