/* Featured Image (Article) */
/* Note: 'featured-image' class is also used in blog card, but article specific styles might conflict if not scoped or if identical. 
   In blog card: min-height 350px.
   In article: height 400px fixed.
   Let's check usage.
   In article.css:
   .featured-image { width: 100%; height: 400px; ... margin-bottom: 40px; }
   
   In blog.css:
   .featured-image { position: relative; min-height: 350px; ... }

   We should be careful. 
   The article page uses <div class="featured-image"><img...></div> inside .article-main.
   The blog index uses <div class="featured-image"> inside .blog-featured.
   
   I will adapt the article's scoped selector to be more specific if possible or just let them cascade. 
   Actually, the article one sets a specific height. 
   Let's make the article one specific to .article-wrapper .featured-image or .article-main .featured-image
