   Guía SHINING en castellano — hoja de estilos principal
   ---------------------------------------------------------------------
   · Sin dependencias externas (ni Bootstrap ni CDN): todo se sirve
     desde doc.shining.es, lo que mejora velocidad y privacidad (RGPD).
   · Sistema de diseño: estilo «Swiss / minimalista» para documentación
     (recomendación ui-ux-pro-max) con la marca SHINING (navy #195097).
   · Tokens en :root; el modo oscuro solo redefine tokens.
   · Accesibilidad: contraste ≥ 4,5:1, foco visible, objetivos ≥ 44 px,
     respeta prefers-reduced-motion.
