/* IFS OPS Web · Kiểu dáng « Nhắn tin hội viên » (10/2026, thread "Nâng cấp giao diện Web") — theo bản mẫu đã duyệt, nền sáng.
   Dùng chung cho trang nhân viên « Tin nhắn » và trang hội viên. File đứng riêng, chỉ có hiệu lực bên trong phần tử có lớp .chat
   (bọc cả hộp thư lẫn khung trò chuyện trong <div class="chat">…</div>), nên tên lớp ngắn như bản mẫu không đụng phần còn lại của web.
   Màu lấy theo bộ giao diện đang dùng (theme.js): --yellow = màu nhấn, --on-accent = chữ trên màu nhấn. */
