   RELATED-POSTS.CSS — Related Articles Grid
   Hello Elementor Child Theme

   Renders a responsive grid of related post cards below the author box.

   Structure:
     section.hec-related-posts
       div.hec-related-posts__header
         h2.hec-related-posts__heading        ("Keep Reading")
       div.hec-related-posts__grid
         article.hec-related-card (× 3)
           a.hec-related-card__thumb-link
             div.hec-related-card__thumb-wrap
               img.hec-related-card__img
               — OR —
               div.hec-related-card__thumb-fallback
                 span.hec-related-card__thumb-fallback-label
               span.hec-related-card__category-badge
           div.hec-related-card__body
             h3.hec-related-card__title
               a.hec-related-card__title-link
             div.hec-related-card__meta
               time.hec-related-card__date
               span.hec-related-card__sep
               span.hec-related-card__reading-time

   Design intent:
     Three-column grid on desktop. Two on tablet. One on mobile.
     Cards have a distinct thumbnail area with an overlaid category badge.
     On hover, the card lifts and the image scales subtly.
     Staggered entrance animations give the grid life.
     Each card is a complete link target — any click navigates to the post.
