//! Widget system demonstration showing containers, panels, and text widgets.
//!
//! This example showcases:
//! - Container layouts (vertical, horizontal, fullscreen)
//! - Panel widgets with headers and borders
//! - Text widgets with different alignments
//! - Auto-centering and padding
//! - Color styling
