/// Enhanced styled! Macro Demonstration
///
/// This demo showcases the enhanced styled! macro with support for:
/// - Basic ANSI colors (original logic)
/// - 256-color palette indices
/// - True RGB colors
/// - Multiple text effects
///
/// The enhanced macro now supports three color formats:
/// 1. Basic colors: Red, Green, Blue, etc. (uses terminal palette)
/// 2. Color256(index): 256-color palette (0-255)
/// 3. Rgb(r, g, b): True RGB colors (0-255 per component)

//# Categories: styling, macros, color, demo
