   Layout:
   - Desktop: sidebar sticky a la izquierda, contenido a la derecha.
   - Mobile: selector horizontal scroll arriba (tipo tabs scrolleables),
     contenido full-width abajo.

   Tipografía: el contenido del manual NO pinta los headings en rojo.
   Los headings son texto bold con tamaño grande, jerarquía visual por
   peso + tamaño. El acento rojo se reserva para el item activo del
