/* ============================================================
   site-chrome.css -- tampilan "bingkai situs" yang SAMA untuk
   semua halaman tool: top bar, breadcrumb, Related Tools, footer.

   Dimuat oleh semua tools/{slug}/index.html (disisipkan otomatis
   oleh apply-site-chrome.php). Ubah file ini SATU KALI untuk
   mengubah tampilan bingkai di seluruh halaman tool.

   Semua class berawalan "stu-" supaya tidak bentrok dengan CSS
   milik masing-masing tool. Warna sengaja netral (tidak ikut tema
   warna tiap tool), kecuali footer yang mewarisi warna footer tool.
