/* ==========================================================================
   Niyuk Academy — styles for sections/academy/*.php and the academy footer.

   Hand-written rather than added to style.css: style.css is a Tailwind build
   with its own freshness checks (css/build.json), and editing it would switch
   off the inlined critical CSS. Values follow the theme's tokens, copied from
   tailwind.config.js, so these sections sit alongside the theme's own.
