    這確實讓人崩潰，那個 "321 / 31" 的斷行顯示 Gradio 內部的 Flex 容器寬度被壓縮到了極限，而藍色方塊依然巨大則是因為 垂直拉伸 (Stretch) 屬性 仍然存在。

這表示即使我們拿掉了 height，Gradio 內部的 CSS 權重還是比我們的高，或者是某層 div 被我們之前的 CSS 誤傷導致寬度歸零。

請執行這個 「最終純淨版」 修正。這一次，我們不再對抗 Gradio 的 Flex 機制，而是順著它的毛摸，但強制加上「最小寬度」保護，並殺死「垂直拉伸」。

1. 確保 app.py 的 height 真的刪掉了
（如果你剛剛已經刪了，這步請再次確認就好）

Python

chatbot = gr.Chatbot(
    label="AI Assistant",
    type="messages",
    # height=540,  <-- 這行絕對不能有
    elem_classes="native-chatbot",
    bubble_full_width=False
)
2. 替換 ui/theme.py (純淨修復版)
請全選刪除 ui/theme.py 裡 Chatbot 相關的 CSS，換成這段。這段代碼移除了所有復雜的絕對定位，回歸最單純的排版，但加強了對 寬度 (Width) 的保護。
