/* wwwroot/css/terminal.css
   Terminal chrome: a Windows PowerShell console skin (classic PS blue, Cascadia Mono, a
   Windows-style title bar) so agent chat reads as a console session rather than a chat-bubble UI.

   Lifted out of AIArticleStudio.razor when the command center adopted the same look. The class names
   are unchanged from that page so its markup didn't have to move; both pages now share one
   definition rather than drifting apart. */
