   AMUN ARQUITECTURA — Componentes (réplica de los mockups PNG)

   Sistema de medidas: en desktop (≥1000px) 1 unidad --u = 1px del mockup
   (el PNG mide 941px de ancho), así todo escala en el mismo registro
   que la imagen. Cada sección usa como fondo su franja del mockup con los
   textos borrados (tools/build_assets.py) y los bloques HTML se ubican con
   --x / --y / --w en px del mockup.
   En mobile (<1000px) las secciones vuelven a flujo normal.
