/* chat-widget.css
   Styling for the "Ask BLOC" chat widget. Uses the same brand variables
   defined in index.html's :root (--bg, --gold, --border, etc.), so it
   must be loaded on a page that already defines those (currently just
   index.html). To reuse the widget on another page, that page needs the
   same :root variables, this stylesheet, chat-widget.html (the
   button/panel markup), and chat-widget.js.
