   PROYECTO : CampoAventuras — Sistema de Blog por bloques (Fase 1A)

   Estilos de los componentes de bloque. Como el HTML lo genera el sistema
   (clases limpias, sin cards anidadas), el CSS es directo y confiable en
   celular, tablet, PC y TV, en cualquier orientación, con mouse o touch.

   Todo va dentro de .blog-articulo para no chocar con el resto del sitio.
   Usa los tokens del tema (--color-primary, fuentes, etc.) con fallbacks.
