/**
 * Branded launcher for the minimized chatbot.
 *
 * The contrib ai_chatbot "collapsed minimal" state leaves the chat window's
 * top edge visible plus a bare toggle icon; these overrides hide the window
 * entirely and float the navigator pointer icon alone in the corner. Selectors
 * are scoped to .chat-collapsed-minimal so the expanded widget keeps its
 * stock look.
 */

/* Expanded panel: contrib rounds only the top corners
   (.chat-container { border-radius: 8px 8px 0 0 }) and draws a #ccc border line
   across the top/sides of the header (.ai-deepchat--header { border: 1px solid
   #ccc; border-bottom: none }). Round all four corners to 8px so the panel
   matches the .brn-search card (navigator-search.css), and drop the header
   border line. Scoped with :not(.chat-collapsed-minimal) so these never touch
   the 56px circular launcher, and higher specificity than contrib's single-class
   selectors so the overrides win without !important (both stylesheets are in the
   "theme" CSS group). */
