/**
 * Chatbot: launcher, popover shell, and skin for the ai_assistant_ui component.
 *
 * Colours, radii and spacing are ported from the previous deep-chat build
 * (fsj_theme/css/chatbot.css plus the messageStyles/auxiliaryStyle JSON that
 * used to be inlined in ai-deepchat--loom-bot.html.twig) so the widget looks
 * unchanged to users. deep-chat was a web component with a shadow DOM, which
 * is why that styling had to be injected as style strings; ai_assistant_ui
 * renders plain light DOM, so ordinary selectors work.
