   FreshWorksheets unified cross-site chrome (sc-* prefixed).

   The block below (down to "MAIN-SITE ADDITIONS") is a BYTE-IDENTICAL copy of
   the Worksheet Studio's app/layout/site-chrome.css, so the main site's header,
   footer and leaderboard-ad shell render pixel-for-pixel the same as the Studio.
   Source of truth: C:/xampp/htdocs/worksheets_free_studio/app/layout/site-chrome.css
   Do not diverge the shared core; main-site-only rules live in the ADDITIONS
   section at the very bottom (text brand, green Studio pill, subject mega-menus,
   mobile hamburger reveal, and the Main-Home hero + category tiles).
