   PRŮVODCE DETAIL — guide-specific prose, layout, and TOC styles

   a fixed 664px reading column that is ALWAYS dead-center on the
   page, with "V článku najdete" floating in the right margin.
   Kept separate from .article-body/clanek.css on purpose — blog
   articles (clanek-detail.php) are unaffected by this file.

   not just be "close" — it's what makes the breadcrumb land exactly
   under the logo instead of merely converging on very wide monitors.
