   blog-detail.css — Blog / Case Study detail page styles
   Base: 19px → scaled via global.css media queries
   Reuses: .container from global.css. Contact section + header/footer
           are NOT styled here — they come from the shared includes.

   NOTE: .bl-toggle / .bl-tag-amber / .bl-tag-blue / .bl-card / .bl-grid
   etc. are copied 1:1 from the blog listing + case studies stylesheets
   so the reading-mode switch and the "Related Blogs" cards look and
   behave exactly the same as those pages. New page-specific pieces use
   the bd- prefix (article header, hero image, TOC, sidebar).
