{# Unsloth-branded JupyterLab login page. Overwrites jupyter_server's default
   login.html (same overwrite pattern as the favicon/logo). Extends the stock
   page.html so favicon (already the Unsloth icon) and form plumbing stay intact;
   we override the title, hide the stock header, and render a dark centered card
   matching the "Unsloth Dark" (Monokai) theme. The card logo reads
   static/logo/logo.png, which the image build replaces with the Unsloth logo. #}
