/* Brand case study (template-case-study.php). Loaded only on that template.

   Everything is csb- prefixed. The theme's older success-story detail design
   already uses cs-hero, cs-card, cs-quote and friends in main.css, and that
   stylesheet loads first — sharing the names handed this page a navy hero
   with near-black text sitting on it.

   Wears the site's own skin: navy ink, green accents, white cards with the
   soft 16px radius and faint navy border used across the theme, and the same
   container as every other page. Sections alternate a picture against a
   column of text so the page reads as a story rather than a stack of boxes. */
