Web UI:
- Textarea replaces input: Shift+Enter for newline, Enter to send
- Pasted text preserves newlines, tabs, whitespace
- Markdown: ```code blocks```, `inline code`, **bold**, *italic*, auto-links
- File upload button (paperclip icon), files stored in memory with download links
Python CLI client:
- Colored usernames: green for self, cyan for system, unique color per other user
- /file <path> command to upload files
- Multiline messages displayed with continuation indent
- JSON protocol for multiline + file support (backwards compatible)
Server:
- POST /chat/upload for multipart file uploads
- GET /files/<id>/<name> for file downloads
- TCP protocol accepts JSON packets for multiline text and file transfers
- Falls back to plain text for old clients
