echo "- Runtime capability checking before sending\n";
echo "- Type-safe media sending methods\n";
echo "- Graceful fallback support\n";
echo "- Unified API across all channels\n\n";

echo "Best Practices:\n";
echo "1. Always check capabilities before sending media\n";
echo "2. Provide fallback to text notifications\n";
echo "3. Handle exceptions gracefully\n";
