/*
 * BPBytes AI assistant widget.
 * Styling for custom/themes/BPBytes/js/customChatbot.js's panel — kept entirely in CSS (using the
 * theme's own color tokens) rather than the widget's original inline JS styles, so it re-colors
 * automatically whenever variables.css changes. Uses the sidebar's own background token (flat,
 * no gradient) so it stays visually tied to the sidebar's color.
 *
 * The trigger itself is a normal topbar icon button (custom/themes/BPBytes/tpls/
 * _headerModuleList.tpl, id="chatbotButton") styled by the shared .bpbytes-icon-btn rule in
 * topbar.css — only its "panel is open" active state is styled here, via body.bpbytes-chatbot-
 * is-open (see customChatbot.js's setOpen()).

/* Full-height slide-in panel docked to the right edge, opening below the topbar — a "side panel"
   rather than the small floating box this used to be, matching a modern AI-assistant pattern
   (Notion AI / Copilot Chat-style) and giving far more room for a real conversation. No dimming
   overlay behind it on purpose: the whole point is to keep referencing the record/list you were
   just looking at while asking about it. */
