• The JavaScript toggles chat-disabled while an AI request runs, but this stylesheet never defines that class. The input therefore remains interactive, allowing overlapping requests and out-of-order responses; add the message-box rule used by the referenced AI integration demo.

#dx-ai-chat {
    border: none;
    min-height: 300px;
}

• The message template adds a Regenerate button to every bubble, but the stylesheet never hides these controls outside the latest assistant message. As a result, user and older messages expose a button whose handler actually rewrites the last message; add the visibility rules used by the referenced AI integration demo.

#ai-chat-toolbar.dx-toolbar {
    border-bottom: var(--dx-border-width) solid var(--dx-color-border);
    padding: 0 20px;
}

#toggle-drawer-button {
    display: inline-flex;
