   Styles for the /tools hub and each in-browser utility. Loaded only on tool
   pages, on top of main.css. Uses the shared design tokens; teal is reserved
   for the "secure / private" signal, per the brand rules. All icons are drawn
   in CSS (no data: URIs) so the strict img-src 'self' policy is untouched.
