/* ============================================================
   instantpnr.com — Blog stylesheet
   Loaded by blog.php and blog/*.php pages.
   Matches the design tokens from /assets/css/style.css.

   This is hand-written CSS (no Tailwind) so it works with the
   site's existing build. Class names match what the blog PHP
   files emit (bg-gradient-to-br, rounded-2xl, prose, etc.) so
   no markup changes are needed — the styles just start working
   once this file is referenced.
