/**
 * Trill Chat Lite — Chat Launcher (lazy-load bootstrap)
 *
 * Minimal launcher-only styles loaded on page load. The full chat-widget.css
 * bundle is loaded dynamically on first click via chat-launcher.js.
 *
 * Kept in sync with chat-widget.css ".trcl-chat-toggle / .trcl-launcher-*"
 * rules so the button looks identical before and after the lazy load — no
 * visual shift when the full widget initialises.
 *
 * @package TrillChatLite
 * @since 1.2.3
 * @license GPL-2.0-or-later
