   Dream Counselling — brochure carousel + lightbox.
   Split out of blog.css because only the EIT Faridabad post uses it;
   every other /blog page should not have to load this. Uses the same
   design tokens (--accent, --card, --border, --muted, etc.) defined
   in blog.css, so this file must always be loaded *after* blog.css.
