   The homepage loads only the trimmed home.min.css bundle, which predates
   the blog feature and has no .blog-grid/.blog-card rules at all (the
   global 8px grid-gap override in home.min.css already targets .blog-grid
   by selector, it just had no base rule to apply to). Other pages load the
   full main.min.css, which already defines these — the declarations below
   are then simply redundant (identical values, last one wins, no visual
   change). Either way this file is safe to include everywhere.

   Base rules copied verbatim from assets/css/main.css (lines 2197-2213). */
