//! Panels - Lego-style composable panel system
//!
//! This module provides:
//! - AutonomousPanel: Self-contained UI component
//! - Composite patterns: Vertical, Horizontal, Split, Tab, Grid
//! - ChangeNotifier: Observer pattern for panel communication
//! - Detail: Components for detail/edit panels (state machine, semaphore, buttons)
//!
//! Architecture based on Simifactu's Lego Panels system:
//! - Panels are autonomous (own state, UI, logic)
//! - Panels are reusable across windows
//! - Windows compose panels (not inheritance)
//! - Communication via ChangeNotifier (observer pattern)
