   LANDING (propuesta del ingeniero): pantallas nuevas del inicio
   Bloques fusionados (pagina de inicio en 12 secciones)
   Paginas de contenido (sectores/, soluciones/, recursos/)

   Este archivo lo cargan TODAS las paginas: aqui va solo lo compartido.
   Las reglas de secciones que existen unicamente en la portada estan en css/home.css,
   que index.html carga despues de este archivo.

   Reglas de mantenimiento:
   - Un cambio nuevo se agrega en el bloque de su componente, no al final.
   - Si una clase solo se usa en index.html, su regla va en css/home.css.
   - Antes de subir cambios de CSS, comparar capturas (ver DEPLOY-SERVIDOR.md).
