/* ==========================================================================
   ClnSlte — Studio visual refresh  (assets/refresh.css)
   --------------------------------------------------------------------------
   PURE PRESENTATION. Loaded AFTER site.css with media="screen" so that:
     • it never reaches print output, and
     • the HTML export (which copies the page's first <style> block) is
       unaffected. Slide internals (.slide and everything inside it) are NOT
       restyled here, so the live preview, exports and print stay identical.
   No selector here depends on, or changes, any ID / data-* hook the scripts use.
   Delete this file + its <link> tag to roll back completely.
