/* News & blog (/news-and-blog/): announcements read in place, the latest blog articles with their covers whole, topics.
   Same language as Resources: navy hero, red kicker, a sticky bar, straight edges. Covers are never cropped: blog banners
   (1200×627, title set in the image) keep their own ratio; announcement covers of any shape sit whole in a frame whose
   backdrop is the same image, blurred. */
