| # app.py — Gradio ChatInterface (4.31-safe, no deprecated tuples warning) | |
| # - No Blocks wrapper (avoids DuplicateBlockError) | |
| # - Pass our own Chatbot to ChatInterface so it doesn't create a tuples-based default | |
| # - Auto-uses type="messages" on >= 4.37; legacy on 4.31 without errors | |
| # - Mobile CSS: fixed height + scroll + wrapping | |
| # - Version-safe queue() and launch() | |
