Callback registration for custom display handling
Approval callback for dangerous operations
Color palette for consistent UI

Example

rust,ignore

use praisonai::display::{register_display_callback, display_interaction, DisplayType};

// Register a custom callback
register_display_callback(DisplayType::Interaction, |event| {
println!("Agent: {} said: {}", event.agent_name, event.content);
});

// Display an interaction
display_interaction("assistant", "Hello!", None);
