/* ==========================================================================
   Code Block - GeeksForGeeks Style
   Standalone CSS for code blocks in student-facing course content.
   Wraps <pre> elements with language header, copy button, line numbers,
   and Prism.js syntax highlighting.

   This is extracted from studio.css so it can be loaded independently
   without pulling in the full CMS/admin theme.
