   Chat history sidebar — Phase B.
   Fixed-position left panel listing the signed-in user's prior conversations.
   The .auth-signed-only class (toggled by site.js) keeps anonymous users

   Layout pattern: when shown on wide screens, body.has-sidebar adds left

   screens (<= 900px), the sidebar becomes an overlay above content with a
   click-to-dismiss backdrop.
