/* ===================================================================
 * Chatbot VNDC widget — hoàn toàn isolated khỏi theme/Elementor.
 *
 * Chiến lược chống đè CSS:
 *   1. Mọi selector đều bọc trong #gau-chatbot-vndc-root  →  specificity 0,1,X
 *      (vẫn thua selector !important của theme, nhưng thắng selector
 *       element thường như `button {}` hoặc `.content button`).
 *   2. Trên các property visual mà theme HAY đè (background, border,
 *      box-shadow, outline, color, text-shadow, text-transform), ta nhét
 *      !important để khoá cứng.
 *   3. all: revert ở khối reset để xoá các property kế thừa mà theme set
 *      trên ancestor — vd theme set `body * { letter-spacing: 2px }`.
 *
 * Class prefix: .gau-chatbot-* (BEM với __ và --).
 * CSS variable prefix: --gau-chatbot-* (JS inject color từ config.php).
